In some cases, copolymerization is used. Typical of the products made in this way are terpolymers of ethylene, n-butyl acrylate, and maleic anhydride, such as the Lotader products from Arkema, which have proved to be very good coupling agents in filled EVA copolymers. 

Ethylene-n-butyl acrylate (EBA) copolymers. EBA copolymers are also widely blended with olefin homopolymers to improve impact strength, toughness, heat sealability, and to promote adhesion. The polymerization process and resultant repeat imit of EBA are shown in Fig. 1.26. 

Olefin copolymers are a group of polyolefin thermoplastics made by copolymerization of olefiiuc polymers. This family includes polyallomers, ionomers, ethylene vinyl acetate (EVA), ethylene ethyl acrylate (EEA), ethylene n-butyl acrylate, ethylene hexane (EH), and ethylene butene (EB). 

The product mix of autoclave and tubular reactors are similar in terms of LDPE homopolymers (0.910-0.935 g/cc) and some specialty grades of polyethylene such as ethylene/vinyl acetate copolymers up to about 30 wt% vinyl acetate (VA). However, the autoclave process provides higher levels of vinyl acetate (40 wt%) in ethylene/VA copolymers and additional specialty grades of polyethylene such as ethylene/methyl acrylate, ethylene/acrylic acid and ethylene/n-butyl acrylate. Polyethylene molecular weight can be varied over a wide range with the high-pressure process, with Melt Index values (I ranging from 0.15 to 40.

In a similar way, n-butyl acrylate was copolymerized by ATRP with methacrylate macromonomers containing highly branched polyethylene prepared by Pd-catalyzed living ethylene polymerization. The observed reactivity ratios depend on the molecular weight and concentration of the macromonomer. The resulting graft copolymers showed microphase separation by AFM [304].

Vinyl resins - In the coatings industry, vinyl resins usually refer to either poly(vinyl chloride) (PVC) or poly(vinyl acetate) (PVAc) which is widely used in interior and exterior latex paints. Produced usually by emulsion polymerization, a PVAc homopolymer is too hard to allow its colloidal latex particles to coalesce well into a continuous film at ambient temperatures. Most PVAc emulsions used in the paint industry are copolymers with a plasticizing monomer such as dibutyl maleate, 2-ethyhexyl acrylate, n-butyl acrylate, dibutyl fumarate, isodecyl acrylate, or ethyl acrylate. By polymerizing under pressure, copolymers of vinyl acetate and ethylene are also produced for latex paints. External plasticizers such as dibutyl phthalate are used as well. All these methods not only soften the polymer to allow the latex particles to coalesce into a continuous film, but also impart the film flexiblity needed in exterior house paints. 

Metal-organic complexes and amorphous fluoropolymers used as catalysts in many organic syntheses exhibit excellent solubility in ScCO [9]. Fluoropolymers such as poly(chlorotrifluoroethylene), fluorinated polyacrylates, copolymers of fluorinated acrylates with methacrylate, n-butyl acrylate, styrene, ethylene, etc. which are used to enhance the solubility of the catalyst are also reported to be highly soluble in SCCO2 [9]. Temperature and pressure dependent catalyst solubility not only enhances its activity, but also permits easy recovery and recycle of the catalyst at the end of the reaction. It is possible to precipitate the catalyst and sometimes the product by suitable adjustments in temperature and pressure, and integrate reaction and separation.
