A new kind of organic compound, α,α' Bis[p (dimethylamino) phenyl] p cresol methacrylate, was synthesized and characterized by FT-IR, 1H-NMR, TGA-DTA and EA. It's m.p. is 100-102 ℃ and it's structure was proved by 1H-NMR and EA. It's copolymer with ethyl acrylate was also synthesized by radical copolymerization, which was characterized by UV-Vis. A series of it's coplymers with methyl methacrylate were also synthesized by radical copolymerization. Then, the glass transition temperatures and thermal stability of the copolymers were determined by DSC and TGA. The hydrolysis properties of the copolymers were also studied and the results showed that the hydrolytic rate is very low.
