Preparation A Cross-Linked Copolymer By Using Unsaturated Poly(2-Butene Maleate) Polyester and Methyl Methacrylate

In this study, synthesis of unsaturated Poly(2-Butene Maleate) polyester by condensation polymerization and preparation cross-linked graft copolymer with methyl methacrylate are presented. For purpose, polyesters were synthesized in four different time periods (12h, 24h, 36h, 48h) the presence hydroquinone using 1,4-Butanediol-2-ene maleic anhydride. Then, obtained was purified on alumina column used to obtain methacrylate. Here in, acts as both co-monomer cross-linking agent.
 Maleate), optimization study molecular weight yield ratios parameter carried out. results obtained, it observed that maximum reached after almost 36 hours (Mn=3400). It did not have much effect yield. Structural characterizations products supported FT-IR NMR analyzes. thermal analysis, stability Cross-linked is higher than but lower pure Poly(methyl methacrylate).
