Title:
PREPOLYMER AND ITS PRODUCTION
Document Type and Number:
Japanese Patent JPH04130125
Kind Code:
A
Abstract:
PURPOSE:To obtain a prepolymer which is highly sensitive, can be cured with light, heat or the like within a short time and is not sticky before being cured by reacting an epoxidized liquid polybutadiene/sec. amine adduct with an unsaturated isocyanate compound. CONSTITUTION:A liquid polybutadiene is epoxidized with, e.g. peracetic acid, followed by an addition reaction with a sec. amine (e.g. dimethylamine). The amount of the sec. amine added is suitably 3-350mmol per 100g of the polybutadiene. The obtained epoxidized liquid polybutadiene/sec. amine adduct is reacted with an unsaturated isocyanate compound (e.g. a reaction product of 2,4-tolylene diisocyanate with 2-hydroxyethyl acrylate) to obtain a prepolymer. The obtained prepolymer can desirably be used for coating materials, inks, resist materials, etc.
