摘要： A polymer obtained by the polymerization of a substituted 1,3-butadiene compound of the formula: ##STR1## wherein each of X.sub.1 and X.sub.2 is hydrogen or SiR.sub.1 R.sub.2 R.sub.3, provided that at least one of X.sub.1 and X.sub.2 is SiR.sub.1 R.sub.2 R.sub.3, wherein each of R.sub.1, R.sub.2 and R.sub.3 is halogen, lower alkyl or lower alkoxy, provided that R.sub.1, R.sub.2 and R.sub.3 are not lower alkyl at the same time.

摘要： A cyclic sulfur compound represented by the formula, ##STR1## wherein R is --CH.sub.2 CH.sub.2 O).sub.n CH.sub.2 CH.sub.2 --, m is an integer of 2 to 4 and n is an integer of 1 to 3 is novel and can be used as a crosslinking agent instead of sulfur per se and also as a monomer for preparing polysulfide polymer. Said cyclic sulfur compound can be produced by reacting a metal sulfide represented by the formula, ##STR2## wherein R is the same as defined above, R' and R" are independently selected from alkyl groups and aryl groups and M is silicon or tin, with a halogen, sulfur dichloride or sulfur monochloride.
