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 or 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## and further provided that none of the hydrocarbon groups has non-aromatic unsaturation.
具有反应性羧基的某些乙烯基不饱和可聚合单体可用于制备用于各种用途的同聚物和共聚物,包括诊断检测。聚合物可以作为水性组合物中的乳胶粒子提供。单体由以下结构表示:##STR1##其中:R为氢,卤素或1至3个碳原子的烷基,M为氢,碱金属离子或铵离子,L为具有8至50个原子的连接链中的连接基,并包括两个或多个二价碳氢基团连接或终止于一个或多个氮、氧或硫原子,或包含这样的原子的基团在连接链中,前提是L至少有一个芳基,该芳基未直接连接到末端##STR2##并且进一步提供,没有任何碳氢基团具有非芳香不饱和性。
