“…Unfortunately, comparing with solvent-type adhesives, vinyl acetate-acrylate latex film exhibits a bad resistance to solvent, and a relatively poor tensile strength because of the presence of surfactant and the influence of the undesirable dispersion of he latex particles, which limit its further application in some areas such as packaging and coating. Recently, many efforts have been made to modify latexes through cross-linking reactions [5][6][7][8][9][10] . The corresponding studies show that the physical properties, chemical stability as well as its tensile strength and resistance to abrasion of latex film, can be greatly enhanced when some cross-linking structures are introduced into the emulsion copolymers.…”

The functional acrylate monomer (FAM) containing an amino group was synthesized by using glycidyl methacrylate (GMA) and ammonia. FAM was then copolymerized with Vinyl acetate and other acrylate monomers by emulsion copolymerization. The cross-linkable latex was obtained by adding a set content of glutaraldehyde to the earlier copolymer emulsion. The FT-IR results show that the cross-linking reaction between amino and aldehyde groups is detected during the curing process of copolymer. The glass transition temperature (T g ) of the copolymer can be evidently increased from À16.2 to À8.7 C as the FAM alters from 0 to 10%. T-peel strength of the polyethylene-polyethylene (PE-PE) packaging films laminated by products was studied. The results show peel strength dramatically increases with the cross-linking density at room temperature, and still reaches 2.5 N Á 15 mm À1 even at 60 C, which can satisfy the application requirement enough.

“…Such surfaces as required for film formation from an academic point of view are far from the typical everyday surfaces that the developed final coatings are typically used on. [5,[7][8][9] These properties are affected not only by the nature of the polymers, but also by film preparation and conditioning. As an example, emulsion polymers typically contain an emulsifier, which may not be uniformly dispersed throughout the full thickness of the film or, due to incompatibilities, may exude from the polymer.…”

Summary: In the present study, reaction components such as emulsifiers, emulsifier combinations, and initiators were used for the particle stabilization of water-borne vinyl acetate -butyl acrylate copolymer latexes. The effects of these parameters on the colloidal film-forming properties of the vinyl acetate-co-butyl acrylate latex colloidal, physicochemical, surface, and film forming properties were investigated, in particular the aspect of their surface coating applications.

“…One approach to improve the balance in the properties of waterborne resins against solvent‐based coatings is to introduce functional groups in polymers, which are able to form crosslinks under an appropriate cure condition and to form thermosetting films. A number of functional groups have been reported for latex coatings in recent years,4–12 for example epoxy groups, N ‐methylolacrylamide groups, N ‐(isobutoxymethyl)‐acrylamide, hydroxyl groups, silanol groups, carboxyl groups, amino groups, blocked isocyanates and acetoacetate groups. Some functional groups like silanol groups or N ‐(isobutoxymethyl)‐acrylamide will self‐react under suitable reaction conditions, whereas other functional groups require the addition of a multifunctional reactant to introduce crosslinking.…”

“…Another approach to improve the performance of waterborne acrylic resins and to satisfy the chemical and physical properties required in various applications is to adopt multiphase polymeric systems. Multiphase polymeric materials exhibit properties that are often superior to those of their component homopolymers due to their morphological structure 1, 12, 13, 15, 16. The polymerization techniques include interpenetrating polymer networks (IPNs) or seeded emulsion polymerization.…”

Functional poly[styrene‐co‐(2‐ethylhexyl acrylate)‐co‐(1,6‐hexanediol diacrylate)]/poly[(methyl methacrylate)‐co‐(butyl acrylate)‐co‐(methacrylic acid)‐co‐(diacetone acrylamide)] (PS/PA) semi‐interpenetrating polymer networks (semi‐LIPNs) containing ketone carboxyl groups were synthesized by two‐stage emulsion polymerization, and characterized by Fourier transform infrared, transmission electron microscopy, dynamic light scattering and DSC. A unique feature of the PS/PA semi‐LIPNs is their ability to crosslink and form thermosetting full‐IPN polymers through the reaction of ketone carboxyl and hydrazide in the course of film formation at ambient temperatures. Series of latex particles with various levels of crosslinking density in the PS and PA domain and varied composition of PS/PA LIPNs were obtained. The effects of the LIPN PS/PA composition and the level of crosslinking density in the PS and PA domain on film density, swell ratio, mechanical properties and contact angle with water were investigated. Maximum synergy effects obtained at around 50/50 (PS/PA) in terms of mechanical properties, density and contact angle with water indicate that the maximum degree of interpenetration is obtained at this composition.
