UNSATURATED POLYESTER-URETHANE PREPOLYMER AND ITS APPLICATIONS |
摘要 |
The present invention relates to an ethylenically unsaturated prepolymer containing at least one condensation-reactive terminal group X selected from hydroxyl and/or amine or free isocyanate moieties, and optionally an ethylenically unsaturated terminal group X', the prepolymer being the product of reaction of the following components A and B: A) a first component A comprising the following mixture: i) at least one first ethylenically unsaturated resin carrying specific amine and/or hydroxyl reactive terminal groups, and/or ii), if appropriate, in the presence of at least one second resin different from the resin i) and selected from: ethylenically unsaturated hydroxyl-containing resins, and/or saturated, hydroxyl-containing and/or amino-containing resins, and/or iii) if appropriate, at least one third, reactive saturated resin, iv) optionally, at least one monoalcohol with unsaturation up to 30 equivalent % of the OH + NH<SUB>2</SUB> total, B) a second component B comprising at least one polyisocyanate with a functionality of 2 or more than 2, the proportions of A and B being such as to prevent any gelling by crosslinking. The invention also relates to a crosslinkable resin composition comprising at least one prepolymer according to the invention, and its uses in various fields of application. |
