Studies on grafting glycidyl methacrylate on polyvinyl chloride backbones

Abstract

Graft copolymers of glycidyl methacrylate on polyvinyl chloride backbones were prepared by the free radical technique. Three types of backbones were used: (1) vinyl chloride homopolymer; (2) copolymer of vinyl chloride–vinyl acetate, 87:13; (3) copolymer of vinyl chloride–vinylidene chloride, 89:11. The grafting reactions resulted in products with lower intrinsic viscosities than the unreacted backbones. The graft copolymers were fractionated with the separation of glycidyl methacrylate homopolymers from the rest of the graft products. Unreacted backbones were separated through gelation of all the epirane‐bearing chains. Structure proof was conducted by chemical cleavage of the grafted side chains by reduction with LiAlH4 and through acid hydrolysis.

Synthesis, characterization and investigation of dielectric properties of two-armed graft copolymers prepared with methyl methacrylate and styrene onto PVC using atom transfer radical polymerization

“…Several synthetic methods for grafting of PVC have been reported by radical chain transfer reaction, such as in grafting of PVC with glycidyl methacrylate [9], methyl methacrylate [10] and butyl acrylate [11], by ionic polymerization from labile chlorine in PVC, such as in the grafting with isobutylene [12], by aid of polyperoxy radical [13], and by aid of electrochemical polymerization [5] in the grafting with aniline. Grafting of styrene and various acrylates was achieved by ATRP with the chloroacetyl group introducing to the polymer as initiating sites [14].…”

Synthesis and characterization of poly(vinyl chloride‐co‐vinyl acetate)‐graft‐poly[(meth)acrylates] by atom transfer radical polymerization

“…Replacing chlorine atoms of PVC with other atoms or groups would yield new polymer properties (or effects), such as thermal stability, polymer–solvent interactions, and dielectric response. Much research has been conducted on the graft copolymerization of PVC since the 1960s 3–6…”

Metal-catalyzed living radical graft copolymerization of olefins initiated from the structural defects of poly(vinyl chloride)

“…Poly(vinyl chloride) (PVC) is one of the most widely used vinyl polymers in the world 2. The anionic,3 cationic,4 and free‐radical5 graft copolymerizations of unmodified PVC have been studied since the 1960s. For the free‐radical graft copolymerization process, it was thought that grafting occurred by the transfer of growing or primary radicals to the main chain of PVC via an abstraction of a chloride or tertiary hydrogen and subsequent initiation from the PVC radicals, by the addition of the growing polymer radical to the terminal double bonds of the PVC backbone, or both 5.…”
