    摘要： (Meth)acrylic polymers having alkenyl or curable silyl groups at the chain ends in high functionality ratios are prepared by a process which comprises (i) preparing a (meth)acrylic polymer having halogen atoms at the chain ends, using an organohalogenated compound or a halosulfonyl compound as an initiator and a metal complex catalyst wherein the central metal atom is selected from the group consisting of the elements of Groups 8, 9, 10 and 11 of the periodic table; and (ii) transforming the halogen atom into an alkenyl group- or a curable silyl group-containing substituent. The obtained (meth)acrylic polymers form homogeneous curing materials.

    摘要： A water-based chipping-resistant paint which comprises 30 to 65 weight percent of solid matter and 0.1 to 10 weight percent of low-temperature volatility solvent as a water-based dispersion substance and wherein the solid matter contains 15 to 75 weight percent of film-formable resin, 0.2 to 25 weight percent of thermoexpandable microspheres, and 20 to 80 weight percent of chipping-resistant material, facilitates vaporization of water at the time of film formation owing to mixing of the low-temperature volatility solvent, can prevent cracking and blistering of a film due to water remaining in the film and vaporization of water remaining after the film formation, and readily form a thick film owing to an expansion effect of the thermoexpandable microspheres at the stage of baking after coating, and therefore is suitable for a chipping resistant underbody coating for automobiles.
