초록

Quater polymer(MBHA) containing two types of acrylic functional group, acetoacetoxyethyl methacrylate(AAM) and 2-hydroxyethyl acrylate was prepared. Then, the MBHA was blended with polyisocyanate type Desmodur IL as a curing agent. Thereafter the mixture was cured at room temperature to get high solid acrylic/polyisocyanate. The MBHA was synthesized at 150℃ for 6 hours typically, and the final conversion reached 87-88%. Lowering Tg and increasing AAM amount in the MBHA resulted in high value of conversion. There was no difference in conversion with the variations of OH values. From the results of physical property tests, MIHS coating was proved to be a good automotive top-coating material.
