This invention deals with new unsaturated ester-amides of .alpha.,.beta.-unsaturated polycarboxylic acids derived from halogenated alcohols of the formula ##EQU1## wherein R is a divalent hydrocarbon moiety having at least one and no more than 10 carbon atoms, X is a member selected from the class of bromine and chlorine, and R' is a member selected from the class of hydrogen and a monovalent hydrocarbon containing at least one and no more than 20 carbon atoms. Typical ester-amides are the maleates, fumarates, itaconates and citraconates. These monomers possess fire-retardant properties and are useful for the synthesis of polymers and copolymers.
这项发明涉及从卤代醇衍生的α,β-不饱和多
羧酸的新不饱和酯酰胺,其
化学式为##EQU1##其中R是至少一个但不超过10个碳原子的二价碳氢基团,X是从
溴和
氯中选择的成员,R'是从氢和含有至少一个但不超过20个碳原子的一价碳氢基团中选择的成员。典型的酯酰胺包括
马来酸酯、
富马酸酯、顶冠酸酯和
柠檬酸酯。这些单体具有阻燃性能,并可用于合成聚合物和共聚物。
