Synthesis and Application of Reactive Acrylic Latexes: Effect of Particle Morphology

Abstract

The aim of the study is the synthesis and characterization of epoxy functional reactive polyacrylic latexes, e.g., poly (BA-co-MMA-co-AN-co-GMA) with core/shell and non-structured (random) particle morphologies. Additionally, their performance as binders and coating ability in leather finishing were studied. The epoxy functional polymers were synthesized via the seeded emulsion polymerization technique and the obtained latexes were characterized by means of particle size, zeta potential, FTIR, TEM, DSC, DMTA, and TGA. The results showed that the particle size and zeta potential values were very similar for both latexes, except core/shell latex had slightly higher particle size. DSC, TEM, and DMTA studies verified the successful synthesis of core/shell latex morphology. The copolymer films were elastic in nature and had low Tg values (−13 and −20 °C). The performance results showed some different behavior for core/shell and random copolymer coatings. The abrasion resistance of the leather finish with random copolymer as binder exhibited slightly better values, especially in wet conditions. On the other hand, the leathers finished with core/shell binder showed better performance in flexing endurance and the water spotting test.

A circular bioeconomy approach for post-bioadsorbent materials from the removal of domestic wastewater contaminants as potential reinforcements

“…Currently, studies are exploring polymerizable thermoplastic resin matrices, such as acrylic-based resins [11,12]. Acrylic-based resins exhibit strong adhesion to different substrates, resistance to aging, light stability, effective pigment binding, easy application, and cost-effectiveness, making them advantageous for composites [13]. Within the framework of the circular bioeconomy, it has been recognized that OPEFBF can be e ciently applied in several areas such as composting, water treatment, and composite reinforcement, etc.…”

A two‐stage analysis for the role of fiber size in terms of length distribution on the performance under accelerated weathering tests of oil palm empty fruit bunch fiber‐reinforced vinyl acrylic composites

“…Besides, it is important to highlight that, regarding NFRPCs, vinyl acrylic thermoplastic matrices have not yet been explored in depth even though they are versatile polymers capable of offering a wide range of properties to meet different in-service requirements (e.g., color stability, transparency, acid and alkali resistance, excellent adhesion to various substrate types, softness and flexibility over a wide temperature range, ease of application, and so forth). 15,16 PDNFs originated from agro-industrial processes as by-products or biomass waste, as is the case of OPEFB, frequently entail multiple environmental impacts, such as water and soil contamination, mainly due to both their inadequate final disposal and their lack of use. 17,18 In this vein, the recovery and valorization of these by-products have been turning into an important focus of research during the last decade because of the following facts.…”

“…Under these circumstances, both the individual and combined effects of ultra‐violet and salt‐fog aging treatments on the performance of OPEFB/vinyl acrylic thermoplastic composites were investigated. Besides, it is important to highlight that, regarding NFRPCs, vinyl acrylic thermoplastic matrices have not yet been explored in depth even though they are versatile polymers capable of offering a wide range of properties to meet different in‐service requirements (e.g., color stability, transparency, acid and alkali resistance, excellent adhesion to various substrate types, softness and flexibility over a wide temperature range, ease of application, and so forth) 15,16 …”

One-Step Synthesis of Self-Stratification Core-Shell Latex for Antimicrobial Coating

“…The synthesis of latex particles with a core-shell morphology is an area of prevalent research that has been receiving extensive attention [ 21 , 22 , 23 , 24 ]. Due to ionic bonding [ 25 ], grafting, or interpenetrating networks [ 26 ] between the core and the shell layer, particles with a core-shell structure can improve the impact resistance, abrasion resistance [ 27 ], water resistance [ 28 ], damping properties [ 29 ], and a variety of other properties [ 30 ] of copolymers, unlike non-core-shell-structure copolymers and polymer blends [ 31 ]. Different preparation methods can produce latex particles with different structures from the same material.…”
