Método para producir composiciones de resina de cloruro de polivinilo
摘要
A polyvinyl chloride resin composition contains: from 0.005 to 5 parts by weight of a polyvinyl alcohol having a viscosity average degree of polymerization of from 100 to 3000 and having a ratio Mw/Mn of a weight average molecular weight Mw to a number average molecular weight Mn of from 2.2 to 4.9; and from 0.01 to 5 parts by weight of a zinc compound, based on 100 parts by weight of a polyvinyl chloride resin. A polyvinyl chloride resin composition is thereby provided that enables to obtain a shaped article thereof excellent in thermal stability while being shaped and less colored.
