The present invention provides a block polymer comprising a polyolefin and a hydrophilic polymer, being finely dispersed in resins, in particular polyolefins, without requiring any compatibilizer, and giving thermoplastic resin compositions, said compositions giving moldings having permanent antistatic properties at low block polymer addition levels even when they are produced by a method involving no shearing and having excellent mechanical strength as well as having an excellent compatibility so as to avoid molding or roll pollution at their formation.
The present invention provides a block polymer (A) which has a structure such that blocks of a polyolefin (a) and blocks of a hydrophilic polymer (b) having a volume resistivity of 105 to 1011 Ω·cm are bonded together alternately and repeatedly;
an antistatic agent comprising the block polymer (A);
a resin composition comprising the block polymer (A) and a thermoplastic resin (B); and
a molded product obtainable by coating or printing a molding comprised of a resin composition containing the block polymer (A).
本发明提供了一种嵌段聚合物,它由聚烯烃和亲
水性聚合物组成,可精细地分散在
树脂(特别是聚烯烃)中,无需任何相容剂,并可得到热塑性
树脂组合物,所述组合物在低嵌段聚合物添加量下可得到具有永久抗静电性能的模塑件,即使是通过不涉及剪切的方法生产时也是如此,并且具有极佳的机械强度和极佳的相容性,从而可避免在成型时产生模塑或轧辊污染。
