通过乳液共聚合分别合成了两种具有互补结构的共聚物乳液：聚(甲基丙烯酸甲酯-丙烯酸丁酯-甲基丙烯酸)［P(MMA-BA-MAA)］和聚(甲基丙烯酸甲酯-丙烯酸丁酯-乙烯基吡咯烷酮)［P(MMA-BA-VP)］。通过1H-NMR测定，研究了共聚物组成与单体投料组成的关系；通过FR-IR、DSC、表面能及力学性能测试，研究了P(MMA-BA-MAA)／P(MMA-BA-VP)共聚物复合体系氢键相互作用及其对聚合物性能的影响。结果表明，P(MMA-BA-MAA)／P(MMA-BA-VP)共聚物复合体系存在氢键相互作用，氢键相互作用导致复合体系表面能降低、拉伸强度提高。
Two copolymers, poly(methyl methacrylate-co-butyl acrylate-co-methacrylic acid) and poly(methyl methacrylate-co-butyl acrylate-co-N-vinyl-2-pyrrolidone), with complementary chemical structure were synthesized through emulsion polymerization. Compositions of the copolymers were determined through 1H-NMR. Hydrogen bonding interaction between these two copolymers and properties of the copolymers complex were studied by means of FT-IR, DSC, surface energy, and tensile measurements. The results show that, there exists hydrogenbonding interactions in the copolyemrs complex, and it is the interactions that results in decreasing of surface energy and promoting of tensility of copolymers complex.
