VINYL ETHERS IN UNSATURATED POLYESTER RESINS, VINYL ESTERS AND VINYL ESTER URETHANES FOR STRUCTURAL APPLICATIONS

摘要

The present invention relates to hardening resin compositions based on unsaturated prepolymer, and vinyl ether monomers can cross-link and be used as structural resin with one or more of the other monomer. It is unstable -20 °C of temperature Dao+110 °C that the resin combination, which solidifies by means of the system of free radical, containing unsaturated prepolymer have acid value g every less than 10 mg KOH and vinyl ether monomers according to formula (I) or (II): A-CH=CH-O-R (I) or (A-CH=CH-O) close to ' (II), there is above-mentioned implication using R n. The present invention also relates to prepare this resin combination and application thereof.
