Synthese De Diols Copolyesters (Synthesis of Copolyester Diols)

Abstract

Copolyester diols were prepared in the presence of tetraoctylene glycol titanate as catalyst at 160 - 230 deg C from epsilon-caprolactone and several comonomers such as Emery Empol diol or triol derivatives, epoxides, esters formed by the reaction of an anhydride and an epoxide, or obtained by the condensation of a diol and a diacide. Several of these copolyester diols are less viscous than polycaprolactones diols and are compatible with ester plasticizers. Some of these yielded polyester-polyurethane binders which were evaluated in solid propellants. (Author)
