Synthesis and Characterization of Acrylic Copolymers of 4-Chloromethyl Styrene with Incorporation of Phthalimide Groups and Amination of Resulted Polymers

4-chloromethyl styrene (cms) was copolymerized with different monomers such as methyl methacrylate (mma), methyl acrylate (ma), 2-ethylhexyl acrylate (eha) by free radical polymerization method at 70 ±1°c using ?,?'-azobis(isobutyronitrile) (aibn) as an initiator. the copolymer compositions were obtained using related 1hnmr spectra and the polydispersity of the copolymers were determined using gel permeation chromatography (gpc). the amino copolymers were prepared by treating 4-chloromethy styrene copolymers with sodium phthalimide and then with hydrazine monohydrate. the polymers were characterized by 1hnmr and ft-ir spectroscopic techniques. the glass transition temperature (tg) of all copolymers was determined by dynamic mechanical thermal analysis (dmta). study of dmta analysis showed that chemical modification of 4-chloromethyl styrene copolymers with phthalimide substituent leads to an increase in the rigidity and glass transition temperature of polymers.
