Document Type and Number:
WIPO Patent Application WO/2023/153397
Kind Code:
A1
Abstract:
The present invention provides a prepolymer composition which contains an isocyanate group-terminated prepolymer. The isocyanate group-terminated prepolymer comprises a reaction product between a polyisocyanate component that contains 1,4-bis(isocyanatomethyl)cyclohexane and a polyol component that contains a first macrodiol and a second macrodiol. The first macrodiol has a hydroxyl value of more than 56.1 mgKOH/g but less than 172 mgKOH/g. The second macrodiol has a hydroxyl value of 374 mgKOH/g to 561 mgKOH/g. The ratio of the second macrodiol relative to the total mole of the first macrodiol and the second macrodiol is 30% by mole to 55% by mole.
