Synthesis and Characterization of Acrylic Copolymers of 4-Chloromethyl Styrene with Incorporation of Phthalimide Groups and Amination of Resulted Polymers |
|
| چکیده انگلیسی مقاله |
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 a,a'-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. |
