    摘要： Compounds having the formula ##STR1## wherein R is hydrogen or an acyl radical are prepared by chlorinating 3-acyl-oxazolidin-2-ones, followed by dehydrochlorination and optionally by saponification and reacylation. The compounds are useful as starting material for substitution and addition reactions and as vinyl monomers in homo- and copolymerizations, whereby oxazolidin-2-one rings containing polymers are formed. These polymers can be used as antistatic agents, dyeing auxiliaries and ion exchangers.
