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:
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
group, and further provided that none of the hydrocarbon groups has non-aromatic unsaturation.
某些具有活性羧基的乙烯不饱和可聚合单体可用于制备各种用途的均聚物和共聚物,包括诊断检测。这些聚合物可以作为水性组合物中的胶乳颗粒供应。单体的结构如下:
其中
R 是氢、卤素或 1 至 3 个碳原子的烷基、
M 是氢、碱金属离子或铵离子,以及
L 是一个连接基团,其连接链中有 8 至 50 个原子,由两个或两个以上的二价烃基团组成,连接基团用一个或多个氮、氧或硫原子连接或终止,或在连接链中用一个或多个含有这些原子的基团连接或终止,条件是 L 至少有一个芳基不与末端直接连接。
L 具有至少一个与末端基团不直接相连的芳基,而且没有一个烃基具有非芳香族不饱和性。
