Abstract

A sulfur-containing macromolecule and a method of preparing the sulfur-containing macromolecule comprising a polymerization step are provided, where the sulfur-containing macromolecule contains internal units of formula (I) and the polymerization step is formula (II) wherein n is greater than 1, said precursor comprises alkyne having one or more acetylene groups and thiol having one or more thiol groups; and R is remainder of said thiol excluding said thiol groups, R′ is remainder of said alkyne excluding said acetylene groups, and R and R′ are selected from organic or organometallic groups.
