A novel functionalized polysulfides. Preparation of polysulfides containing spiroorthocarbonate moiety in the main chain.

Preparation of polysulfides containing spiroorthocarbonate structure in the main chain by the radical polyaddition of unsaturated spiroorthocarbonate, 2,7-dimethylene-1,4,6,9-tetra-oxaspiro[4.4]nonane, with dithiols is described.
