氯化聚乙烯的无扰尺寸和氯含量的关系 THE RELATIONSHIP UNPERTURBED DIMENSION WITH C1 CONTENT OF CHLORINATED POLYETHYLENE 田炳寿 Tian Bingshou 1 first-author 程叔耀 Cheng Shuyao 1 陈磊 Chen Lei 1 余蕙 Yu Hai 1 武汉大学化学学院 武汉大学化学学院 College of Chemistry, Wuhan University College of Chemistry, Wuhan University 由高密度聚乙烯的固相氯化法制得含氯量为３７．５％～６７．３％的一系列氯化聚乙烯试样，用ＧＰＣ－［η］联用仪测定了无扰参数Ｋθ，确定了Ｋθ和氯含量（ｘ）及测量温度的关系，它们的关系为Ｋθ＝Ｋｅｘｐ［（Ｂ＋α）Ｘ／２］ｅｘｐ［（Ａ＋β）Ｔ／２］．并从红外光谱得到的结构信息，从分子的微观状态的改变阐明Ｋθ随ｘ的变化． The Unperturbed dimensions have been measused by GPC [ η ] coupled with a capillary viscometer. The series of different chlorine contents between 37.5%￣67.3% were prepared by solid phase chlorination of high density polyethylene. Unperturbed parameter, K θ , bears relations to C1 content and measured temperature, This relation is K θ = k exp（（ B+α）x /2）exp（（ A+β）T /2）. This can be explained by the results obtained from IR spectra. 氯化聚乙烯 无扰尺寸 无扰参数 chlorinated polyethylene unperturbed dimension unperturbed parameter O631.1 1998-04-01 2021-04-01 4
