This invention relates to a highly stable, dense interpenetrated crosslinked polymer network (ICPN) containing (a) a crosslinked, network-forming primary polymer containing vinyl lactam and/or acrylic acid moieties, and (b) a secondary, optionally crosslinked, distinctly different polymer interpenetrated into the network of (a) and derived from a monomer selected from the group consisting of an acrylate and/or acrylamide monomer. The invention also relates to the oil-suspension, sequential polymerization of (a) and (b) for producing the above described interpenetrated polymeric network.
本发明涉及一种高度稳定、密度交错交联聚合物网络(ICPN),其含有(a)交联的、网络形成的主聚合物,其中含有
乙烯内酰胺和/或
丙烯酸基团,以及(b)第二种、可选交联的、明显不同的聚合物,交错地穿插在(a)的网络中,并来源于从
丙烯酸酯和/或
丙烯酰胺单体中选择的单体群。本发明还涉及通过(a)和(b)的油悬浮、顺序聚合制备上述交错聚合物网络。
