Hyperbranched film for styrene resin composition and a styrene-based resin film

摘要

PROBLEM TO BE SOLVED: To provide a styrene-based resin composition for a film that includes a high branched type ultrahigh molecular weight copolymer in which the balance of a melt tension and melt drawability is excellent, and to provide a method of manufacturing the film using the same, and the film.;SOLUTION: The styrene-based resin composition for a high branched type film is a styrene-based resin composition including: a highly branched type ultrahigh molecular weight body that is generated by that the multifunction vinyl compound copolymer and the monovinyl compound are polymerized; and a linear polymer that is generated by that the monovinyl compound is polymerized in a manner that a material solution in which 100 ppm-3,000 ppm by weight of a solvent solubility multifunction vinyl compound copolymer that has two or more vinyl groups in one molecule and a bifurcation structure is added in a monovinyl compound containing styrene, is continuously polymerized, wherein Mw is 200,000-500,000, Mz/Mw is 2.2-5.0, and the branching ratio gM in the molecular weight of 1.0 million-1.5 million is 0.85-0.40.;COPYRIGHT: (C)2013,JPO&INPIT
