Provided is a composition comprising a pre-formed, hydrolytically susceptible non-addition polyanionic polymer comprising polymer strands formed from at least one ethylenically unsaturated monomer and linking the polymer strands by at least one linking moiety comprising a hydrolytically susceptible bond, wherein at least one of which monomers has: i) one or more functional groups that can be titrated with base to form negatively charged functional groups; or ii) one or more precursor groups that are precursors of the functional groups that can be titrated with base; which precursor groups are converted to the functional groups.
提供了一种组合物,该组合物包含一种预成型的、易水解的非加成聚阴离子聚合物,该聚合物包含由至少一种乙烯基不饱和单体形成的聚合物链,并通过至少一种包含易水解键的连接分子将聚合物链连接起来,其中至少一种单体具有以下特征:i) 一个或多个可与碱滴定以形成带负电荷官能团的官能团;或 ii) 一个或多个可与碱滴定的官能团的前体基团;这些前体基团可转化为官能团。
