Synthesis of aromatic dicarboxyl‐terminated poly(methyl methacrylate) macromonomers

Hydroxyl‐ or amino‐terminated prepolymers were prepared by radical polymerization of methyl methacrylate in the presence of 2‐mercaptoethanol or 2‐aminoethanethiol hydrochloride, respectively, as a chain transfer agent. The resulting prepolymers were subjected to react with trimellitic anhydride to form aromatic dicarboxyl‐terminated poly(methyl methacrylate)s. These condensation‐type macromonomers and terephthalic acid were condensed with bisphenol‐A to produce polyester–poly(methyl methacrylate) graft copolymers.
