摘要 通过氢键复合形成的聚(丙烯酸-co-甲基丙烯酸甲酯)/聚乙二醇(P(AA-co-MMA)/PEG)半互穿聚合物网络,其储能模量比(Eg/Er)可以达到160,相应的损耗因子(tanδ)高达1.0242。其最大应力随着分子量的增加逐渐增大;断裂时应变随着PEG分子量的增加逐渐增大。 The poly ( acrylic acid - co - methyl methacrylate )/poly ( ethylene glycol ) ( P ( AA - co - MMA)/PEG) semi- IPN stabilized by hydrogen bonds are prepared. Its storage modulus ratio (Eg/Er) and loss tangent (tand)can reach to 160 and 1. 0242,separately. The maximum stress and the elongation at break increase with increasing of molecular weight of PEG.
