“…Plastisol formulations are made of a suspension of PVC particles in a liquid continuous phase composed of plasticizer, adjuvants such as stabilizers, pigments, blowing agents, and mineral fillers . The PVC plastisols can be processed by different techniques such as dipping, cast molding, extrusion, spraying, and screen printing , and they are often coated at ambient temperature on textile substrates followed by its simultaneous or subsequent heating . Herein, we first studied the spectral properties of the PVC plastisol formulation described in Table , and the same one without fillers 1 and 2 (Fig.…”

Plastisol is mostly a suspension of PVC particles in a liquid plasticizer that flows as a liquid and can be poured into a heated mold. For PVC plastisol applications, in addition to liquid dispersion performance and postdispersion flocculation resistance, outdoor durability is an important end use requirement. Spectral properties of PVC plastisol-based films with or without additional near infrared (NIR) rays barrier fillers have been investigated. Both spherical and lamellar fillers have been incorporated in PVC plastisol at a weight content of 2% to 10% and results show a high impact on the reflectance in the NIR region and on the transmittance in the visible (Vis) region. Experimental results showed that the incorporation of nacre lamellar-based filler in PVC plastisol did not permit favorably change its spectral properties while TiO 2 -based particles ensured a decrease of the transmittance in the Vis and an increase of the reflectance in the NIR.

“…According to Rybachuk et al[3], PVC plastisols can be classified in three different categories: (a) low viscosity plastisols (1–5 Pa·s), (b) middle viscosity plastisols (5–15 Pa·s), and high viscosity plastisols (15–1000 Pa·s). Low and middle viscosity plastisols are adequate for casting molding operations, including rotational molding.…”

“…The PVC plastisols can be processed by different techniques [1–3], for example, dipping, cast molding, rotational molding, extrusion, spraying, spreading, and screen printing. In general terms, all of these processing methods involve the distribution of the plastisol, when it is still a liquid, on a substrate and its simultaneous or subsequent heating.…”

Plastisols based on polyvinyl chloride (PVC) can be processed by different techniques; their processability markedly depends on their flow properties and gelation/fusion processes. Classically, PVC has been the only polymer present in plastisol formulations. The present work explored the possibility of adding polyhydroxyalkanoates (PHAs), a type of biopolymer that, according to previous work, exhibits a good miscibility with PVC processed by other techniques (internal mixer and compression molding). The influence of PHA particles on flow properties, gelation‐fusion processes, tensile strength, hardness, and processability by rotomolding was evaluated. Although the biopolymer markedly increased the viscosity of PVC plastisols and caused a decrease in tensile strength in processed specimens, formulations including 20% by weight of biopolymer presented a good thickness distribution in rotomolded items, an elongation at break of around 300%, and an ultimate tensile strength of around 6–7 MPa.

“…Particle morphology has a considerable infl uence on the combination of the polymer with plasticisers [15]. Therefore, the need arises to study the process of swelling of PVC particles in plasticisers and to establish the possibility of controlling the process of their combination.…”

Translated by P. CurtisThe main method for processing polyvinyl chloride (PVC) is plastisol technology [1] in which the process of combination of the polymer with the plasticiser is determined by the structure of the PVC. It is well known [2,3] that the structure of emulsion PVC is infl uenced substantially by the method of formation from latex. Here, a promising means of polymer formation is coagulation by cationic polyelectrolytes. The principle of action of these reagents is based on the destabilisation of latex particles by neutralisation of the protective layer created by the emulsifi ers, as a result of which the destabilised polymer particles form a precipitate to be separated from the mother liquor [4].The advantages of polymer formation by cationic polyelectrolytes over spray drying and coagulation by inorganic electrolytes include a lower energy requirement, ecological safety of the process, the absence of contamination of the PVC by polymerisate components and mineral impurities [4,5], and also the possibility of changing the morphology of the polymer. The high activity and selectivity of cationic polyelectrolytes lower the coagulant consumption considerably compared with inorganic electrolytes [6,7]. In this connection, the study of the process of PVC latex coagulation is urgent from the point of view of controlling the structure and properties of the polymer, which infl uence its combination with plasticisers.This article presents a comparative analysis of the properties of plasticised systems according to the method of formation of the polymer from latex, and sets out a method for controlling the properties of PVC-plasticiser mixtures during the processing of the polymer by plastisol technology.An analysis was made of industrial emulsion PVC of grade PVC-EP-6602S, formed from latex during spray drying (PVC-1), and a polymer specimen (PVC-2) produced as result of coagulation of latex with a polymer concentration C L = 42%, a degree of adsorption saturation θ = 84.1%, and an average particle diameter d av = 184.4 nm. The coagulating agent was a cationic polyelectrolyte -poly-1,2-dimethyl-5-vinylpyridinium methyl sulphate (poly-1,2-DM-5-VPMS) obtained by the procedure described in reference [8].To investigate the process of coagulation, a solution of polyelectrolyte of specifi ed concentration (C PE , mg equ/L) was added to the latex, the system was mixed, and the effectiveness of the coagulating action of the polyelectrolyte was assessed from the degree of precipitation of the polymer (X, %), equal to the ratio of the mass of the precipitated polymer to its total mass in the investigated specimen. The PVC specimens were dried at room temperature.The density of the polymer ρ p was determined picnometrically in isopropyl alcohol at 20 °C according to the procedure set out in reference [9].The degree of crystallinity of the PVC specimens was assessed by X-ray diffraction analysis [9] on a DRON-3.0 X-ray diffractometer.Optical microscopy [10] was used to study the process of swelling of microparticles in ...
