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: Processes for the preparation of a functional polymer of low molar mass, which includes initially charging a first quantity M1 of a mixture including at least one component selected from olefinically unsaturated monomers B and compounds A which are not themselves copolymerizable but which are able to react with at least one of the monomers B to form a copolymerizable addition compound, metering in prior to or during polymerization a second quantity M2 of a mixture whose composition can be identical to or different from that of the first mixture M1 and which includes at least one component selected from olefinically unsaturated monomers B and compounds A, initiating polymerization by use of a polymerization initiator and optionally a chain transfer agent, conducting polymerization in the presence of an oligomer or polymer C, wherein the oligomer or polymer C is either formed in situ from one or more of A and B or is dissolved in at least one of the quantities M1 and M2, wherein at least one of M1 and M2 includes a monomer B. The polymers are useful in coating compositions.
