| 摘 要： | 用批量法合成了聚苯乙烯（ＰＳｔ）、聚甲基丙烯酸甲酯（ＰＭＭＡ）、聚丙烯酸丁酯（ＰＢＡ）均聚乳液，以及Ｐ（ＢＡ－Ｓｔ）和Ｐ（ＢＡ－ＭＭＡ）共聚乳液．实验发现极性相近的ＰＢＡ和ＰＭＭＡ乳液可以很好地混合，而极性相差较大的ＰＢＡ和ＰＳｔ乳液则必须在ＰＳｔ乳液中补加乳化剂后方能混合均匀．对乳液最低成膜温度（ＭＦＴ）、胶膜硬度及耐水性的研究表明：质量比为１１的ＰＢＡ／ＰＭＭＡ共混胶膜和Ｐ（ＢＡ－ＭＭＡ）共聚胶膜的连续相组成相近；而对于同样组成的ＰＢＡ／ＰＳｔ共混胶膜，分散在连续相中的ＰＳｔ所占比例明显高于Ｐ（ＢＡ－Ｓｔ）共聚胶膜；ＰＢＡ／ＰＳｔ共混胶乳的使用性能不仅取决于其组成，还取决于成膜温度和使用温度

| Abstract: | Homopolymer latices of polybutyl acrylate (BA),polymethyl methacrylate (MMA),polystyrene (St) and copolymer latices of P(BA St),P(BA MMA) were first synthesized using batch emulsion polymerization,and then blend latices of PBA/PSt and PBA/PMMA were obtained.It was found that the mixing process and stability of blend latex were strongly affected by polymeric polarity and amount of emulsifer in original latex under the present experiment conditions.Minimum formation temperature (MFT) of latices,water resistance and hardness of various films were also studied.It was observed that the properties of PBA/PMMA film were similar to those of P(BA MMA) when weight ratio of BA and MMA unite is 1,but the film properties of PBA/PSt and P(BA St) were significantly different,and these differences can be explained using compatibilites of PBA,PMMA and PSt. |
