Abstract

PURPOSE: To prepare a low-swelling polyester-urethane elastomer composition having excellent solvent resistance and mechanical strength, by the use of a polyester polyol wherein succinic acid is used as a main component of the carboxylic acid.
CONSTITUTION: A polyester polyol having a molecular weight of pref. 500W4,000 and an average number of functional groups of pref. 2.0W3.0, is prepared by the condensation reaction of a polyfunctional carboxylic acid composed mainly of succinic acid (≥70wt%) and an organic polyhydroxyl compound (e.g. diethylene glycol). The polyester polyol is converted to an urethane elastomer having a volume swell of ≤100% in methyl ethyl ketone (25°C, immersion for 48hr), e.g. by prepolymer process.
