Abstract: Methyl methacrylate-naphthyl ethylene copolymer was studied by two dimensional NMR spectroscopy (2D H, X-COSY, NOESY). ¹³C and ¹H chemical shifts of the copolymer were assigned (Tab.2). Results show that the structure of the copolymer is mainly random with respect to the stereochemical configuration, there are some head-head (or tail-tail) copolymers linked by methyl methacrylate and naphthyl ethylene. The content of copolymers was measured by inverse gated heteronuclear decoupling.
