Abstract: Disclosed is a curable resin composition which can be applied for various uses such as top-coating compositions for cars, coating compositions for exterior walls of constructions, heat-resistant coating compositions, adhesives, ink compositions, compositions to be infiltrated into fibers and paper, and surface-treating compositions. The composition comprises (A) a resin obtained by condensation of a polymer having both a hydrolyzable silyl group and a particular functional group except such a hydrolyzable silyl group, and a particular polysiloxane, and (B) a compound capable of reacting with the functional group existing in the resin (A).

Abstract: The invention concerns a process for the production of block copolymers or aqueous dispersions and emulsions thereof, whereby azo macroinitiators are reacted with radical-polymerizable monomers or a mixture of several radical-polymerizable monomers. The azo macroinitiators are obtained by reacting simple reactive azo compounds with prepolymers with a molecular weight between 400 and 20000, which possess at least 2 functional groups, e.g. polyurethanes or polyesters.The aqueous block copolymer dispersions and emulsions produced according to the invention are suitable for use for the production of paints, adhesives etc.
