摘要：
A polyvinyl chloride resin composition contains: from 0.005 to 5 parts by weight of a vinyl alcohol-based polymer having a degree of saponification of not less than 30 mol% and less than 75 mol% and having a viscosity average degree of polymerization of less than 300; 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 is good in thermal stability while being shaped and with which a shaped article of excellent transparency can be obtained.
