Abstract
Plastifiants constitués de polyesters à poids moléculaire élevé. Les plastifiants sont des polyesters saturés, linéaires, solides, à extension de chaîne, à poids moléculaire moyen en nombre d'au moins 40 000 et ayant un rapport radicaux méthylènes/ radicaux carbonyloxy d'environ 4 : 1 à environ 7 : 1; ces polyesters à extension de chaîne, ayant les caractéristiques indiquées ci-dessus, sont préparés par réaction d'un prépolymère en polyester avec un agent d'extension de chaîne. La présente invention est particulièrement utile pour fournir des polyesters avec extension de chaîne, employés comme plastifiants pour des polymères d'halogénures de vinyle.Plasticizers made from high molecular weight polyesters. Plasticizers are saturated, linear, solid, chain-extending polyesters having a number average molecular weight of at least 40,000 and having a methylene group / carbonyloxy group ratio of from about 4: 1 to about 7: 1; these chain-extending polyesters, having the characteristics given above, are prepared by reacting a polyester prepolymer with a chain-extending agent. The present invention is particularly useful for providing chain-extended polyesters used as plasticizers for vinyl halide polymers.
