Abstract
AbstractChloral and cyclic formals were copolymerized in the presence of acidic catalysts and controlled amounts of water to diols of varying compositions and molecular weights. Cyclic oligomers were formed irreversibly as by‐products from the monomers and were also obtained by depolymerization. Condensation of the diols with diisocyanates yielded linear polyurethanes of improved flame resistance.
