Certain ethylenically unsaturated polymerizable monomers having a reactive carboxy group are useful for preparing homo- and copolymers for a variety of uses, including diagnostic assays. The polymers can be supplied as latex particles in aqueous compositions. The monomers are represented by the structure: ##STR1## wherein: R is hydrogen, halo or alkyl of 1 to 3 carbon atoms, M is hydrogen, an alkali metal ion or an ammonium ion, and L is a linking group having from 8 to 50 atoms in its linking chain, and comprises two or more divalent hydrocarbon groups connected or terminated with one or more nitrogen, oxygen or sulfur atoms, or with one or more groups containing such atoms in the linking chain, provided L has at least one arylene which is not directly connected to the terminal ##STR2## group, and further provided that none of the hydrocarbon groups has non-aromatic unsaturation.
某些具有反应性羧基的乙烯基不饱和可聚合单体对于制备用于多种用途的同聚物和共聚物是有用的,包括诊断分析。聚合物可以以乳胶粒的形式在水性配方中提供。这些单体由以下结构表示:##STR1## 其中:R是氢、卤素或1到3个碳原子的烷基,M是氢、碱金属离子或铵离子,L是一个连接基团,其连接链中有8到50个原子,并包含两个或多个二价烃基团,这些基团通过一个或多个氮、氧或硫原子连接或终止,或者通过连接链中含有一个或多个这样的原子的一个或多个基团,前提是L至少含有一个不是直接连接到端部##STR2##基团的芳基,并且进一步提供,没有任何烃基团具有非芳香不饱和度。
