    摘要: A stabilized thermoplastic composition comprised of polyvinyl chloride or mixed polymers containing mainly vinyl chloride units together with stabilizers and other conventional additives employed in thermoplastic compositions, which have as major stabilizer component, a content of 0.02 to 5 parts by weight of aliphatic polyhydroxyl compounds containing 4 to 6 OH-groups per 100 parts by weight of polymer. These polyhydroxyl compounds should contain at least one carboxyl and/or carbonyl group and/or double bond. Suitable compounds are gluconic acid, glucuronic acid, ketogluconic acid, ascorbic acid or the alkali metal salts or alkaline earth salts of the mentioned acids.Other conventional processing additives may be present. The invention concerns also a process for the manufacture of pipes, profiles, foils, hollow parts by hot forming, with the use of the mentioned additives, and the additional use of paraffin, free fatty acid, epoxidized soybean oil or higher molecular weight ester wax.
