Abstract: Prepn. of low mol. wt. functional polymers comprises: (1) preparing a first quantity of a mixt. (M1) from at least one component chosen from olefinic unsatd. monomers (B) and cpds. (A) which do not copolymerise with (B) but can react to form a copolymerisable addn. reaction cpd.; (2) starting polymerisation by the addn. of initiators and opt. regulators; and (3) adding an additional quantity (M2) of the (A)/(B) mixt. during polymerisation, the compsn. of (M2) being the same as or different to (M1), with the provision that an oligomer or polymer (C) is dissolved in at least one of (M1) or (M2), and at least one of (M1) or (M2) contains a component (B). Also claimed are: (i) copolymers prepd. by the process, and (ii) binders for lacquers which contain these copolymers, as well as cross-linking agents chosen from isocyanates, melamine resins or epoxy cpds.

Abstract: Water-dilutable 2-component coating materials (I), contg. (a) an isocyanate component with a viscosity of 50-10,000 mPa.s at 23 degrees C, consisting of polyfunctional isocyanate(s), and (b) an alkyd resin emulsion, contg. (b1) 60-98 wt% alkyd resin(s) (based on solids), (b2) 2-40 wt% OH-functional emulsifier(s) (based on solids), (b3) opt. up to 15 wt% organic solvent (based on emulsion), and (b4) water. Also claimed is: (i) a process for the prodn. of (I) by transferring an alkyd resin into the aq. phase with the aid of OH-functional emulsifiers and then emulsifying polyisocyanate in this emulsion; (ii) a process for the prodn. of coatings using (I); (iii) a process for the prodn. of multilayer coatings, in which at least one of the coating materials used contains (I).
