The invention relates to a polymer which can be obtained by radical emulsion polymerization of at least one acidic vinyl monomer or salt thereof, at least one non-ionic vinyl monomer, in particular preferably a hydrophobic non-ionic vinyl monomer, at least one monomer containing an unsaturated terminal group and a polyoxyalkyene portion, at least one crosslinking monomer, optionally a protective colloid, and is characterized in that the polymerization is controlled such that the gelling effect occurs at least at times, which is achieved by the monomer addition (dosing time) taking place for 40 minutes, particularly preferably for 30 minutes.
本发明涉及一种聚合物,该聚合物可通过至少一种酸性乙烯基单体或其盐,至少一种非离子乙烯基单体,特别是优选疏水性非离子乙烯基单体,至少一种含有不饱和末端基团和聚氧乙烯部分的单体,至少一种交联单体,可选保护胶体的自由基乳液聚合得到、至少一种交联单体,可选择一种保护胶体,其特征在于聚合过程受到控制,胶凝效果至少在一定时间内出现,通过单体添加(定量时间)40 分钟,特别是 30 分钟来实现。
