Preparation of polysulfides containingspiroorthocarbonate structure in the mainchain by the radical polyaddition of unsaturated spiroorthocarbonate, 2,7-dimethylene-1,4,6,9-tetra-oxaspiro[4.4]nonane, with dithiols is described.
Polymers obtained by condensing polyols with divinyl orthocarbonates are useful for making bioerodible polymers for sustained release of beneficial agents.
