摘要

<,正,>, This paper describes the synthesis and free radical ring-opening polymerization of 2-methyl-and 2-methyl-9-n-butyl （-7-methylene-1, 4, 6-trioxaspiro （4, 4） nonane）. The structures of the two polymers were verified by IR, ’H and,13,C NMR spectra. The substituent on 9-position of 7-methylene-trioxaspiro （4, 4） nonane affects the structure of polymer and polymerization activity. The polymerization mechanism is discussed.

Abstract

This paper describes the synthesis and free radical ring-opening polymerization of 2-methyl-and 2-methyl-9-n-butyl （-7-methylene-1, 4, 6-trioxaspiro （4, 4） nonane）. The structures of the two polymers were verified by IR, ’H and ,13,C NMR spectra. The substituent on 9-position of 7-methylene-trioxaspiro （4, 4） nonane affects the structure of polymer and polymerization activity. The polymerization mechanism is discussed.
