多种（A-无规-B）共聚物的玻璃化转变温度 T-g 已通过 d.s.c. 测定，其中 A、B = 丙烯酸甲酯、丙烯酸乙酯、丙烯酸正丁酯、丙烯酸异丁酯、丙烯酸叔丁酯、丙烯酸 2-乙基己基酯、甲基丙烯酸甲酯、甲基丙烯酸乙酯、甲基丙烯酸正丁酯、甲基丙烯酸异丁酯、甲基丙烯酸叔丁酯、分别为丙烯腈、苯乙烯和氯乙烯。 AB 共聚物的组成从 0% (w/w) 变化，步长为 20%，从而产生超过 400 个 T-g 值的数据集。所有类型的 T-g 与成分依赖性均得到恢复，从而产生线性、凸形、凹形和 S 形形状。在大多数情况下，根据戈登-泰勒方程通过单参数拟合可以获得令人满意的数据描述。版权所有 (C) 1996 爱思唯尔科学有限公司
Glass transition temperatures T-g for a wide variety of (A-random-B) copolymers have been determined by means of d.s.c., with A, B = methyl acrylate, ethyl acrylate, n-butyl acrylate, iso-butyl acrylate, t-butyl acrylate, 2-ethyl hexylacrylate, methyl methacrylate, ethyl methacrylate, n-butyl methacrylate, iso-butyl methacrylate, t-butyl methacrylate, acrylonitrile, styrene and vinyl chloride, respectively. The composition of the AB copolymers was varied from 0 to 100% (w/w) in steps of 20%, thus yielding a data set of more than 400 T-g values. All types of T-g versus composition dependence were recovered, resulting in linear, convex, concave and sigmoidaI shapes. In most cases, a satisfying description of the data was achieved via a one-parameter fit according to the Gordon-Taylor equation. Copyright (C) 1996 Elsevier Science Ltd.
