美国聚合物标准品公司(American Polymer Standards Corporation, APSC)专业从事聚合物分子量分布分析,在分析各种材料例如尼龙,聚氨酯,聚乙烯,聚丙烯,共聚物等具有丰富的经验。分子量分布分析的主要方法有凝胶渗透色谱/尺寸排阻色谱(GPC/SEC);多角激光光散射(MALLS) 以及气相渗透压法(VPO)。 自1983年起,美国聚合物标准品公司即提供多种和水性聚合物标准品,这些标准品非常适合于仪器校准,聚合物样品的GPC/SEC,MALLS或VPO的分子量测定。 联系电话:18018625233(同微信) QQ:2303607288
聚甲基丙烯酸甲酯,以丙烯酸及其酯类聚合所得到的聚合物统称丙烯酸类树酯,相应的塑料统称聚丙烯酸类塑料,其中以聚甲基丙烯酯甲酯应用广泛。聚甲基丙烯酸甲酯缩写代号为PMMA,俗称玻璃,是迄今为止合成透明材料中质地异,价格又比较适宜的品种。应用方面:PMMA溶于溶剂,如苯酚,苯甲醚等,通过旋涂可以形成良好的薄膜,具有良好的介电性能,可以作为场效应管(OFET)亦称薄膜晶体管(OTFT)的介质层.。
