The invention provides coating material compositions comprising stable adducts which, at relatively high temperatures, generate radicals that possess initiating activity, and also provides processes for preparing them, and for the use of such coating material compositions. Stable adducts of this kind may be used in order to initiate polymerization of ethylenically unsaturated monomers.

Coating compositions

A reaction product (A) which can be prepared by reaction, under free radical conditions, of at least one monomer (a) capable of free radical reaction, in the presence of at least one free radical initiator and of a radical of the formula (III)where Rto R, in each case independently of one another, are hydrogen, methyl or a radical-stabilizing and/or bulky group selected from an unsubstituted or substituted, linear or branched alkyl of two or more carbon atoms, cycloalkyl, alcohol, ether, polyether, amine, aralkyl radical, a substituted or unsubstituted aromatic, heterocyclic or olefinic hydrocarbon, a halogen atom, a substituted or unsubstituted, linear or branched alkenyl or alkynyl group, &#x2014;C(O)R, &#x2014;C(O)OR, &#x2014;CRR&#x2014;O&#x2014;R, &#x2014;O&#x2014;C(O)R, &#x2014;CN, &#x2014;O&#x2014;CN, &#x2014;S&#x2014;CN, &#x2014;O&#x2014;C&#x2550;NR, &#x2014;S&#x2014;C&#x2550;NR, &#x2014;O&#x2014;CRR&#x2014;CRRNRR, &#x2014;N&#x2550;C&#x2550;O, &#x2014;C&#x2550;NR, &#x2014;CRR-Hal, &#x2014;C(S)R, &#x2014;CRR&#x2014;P(O)RR, &#x2014;CRR&#x2014;PRR, &#x2014;CRR&#x2014;NRR, &#x2014;CRR(OR)(OR), &#x2014;CRR(OR)(NR), &#x2014;CRR(NR)(NR), an anhydride, acetal or ketal group, &#x2014;SOR, an amidine group, &#x2014;NRC(S)NR, &#x2014;NRC(S)&#x2014;OR, &#x2014;N&#x2550;C&#x2550;S, &#x2014;NO, &#x2014;C&#x2550;N&#x2014;OH, &#x2014;N(R)&#x2550;NR, &#x2014;PRRR, &#x2014;OSiRRRor &#x2014;SiRRR, where Rto R, independently of one another in each case, are defined in the same way as Rto R, or two of the radicals Rto Rform a C- to C-ring which in turn may be substituted or unsubstituted and, if required, may contain one or more heteroatoms, with the proviso that at least two of the radicals Rto Rare a radical-stabilizing and/or bulky group as defined above, has various uses.

Use of polymeric reaction product

Method for producing a polymeric conversion product

A process for the preparation of polymers is described, wherein at least one first ethylenically unsaturated monomer is subjected to a free radical polymerization in the presence of stable free radicals or sources of stable free radicals and of a compound having at least one free thiol group to give a polymer, and wherein the molar ratio of compound having a free thiol group to stable free radicals is from 0.05 to 1.1. The polymerization rate is substantially increased by the compound having a free thiol group.

Method for producing polymers

The invention relates to a coating agent, containing at least one conversion product (A) and at least one suitable additive (C), (A) being produced according to a method comprising the following step (i): (iv) reacting a reaction mixture comprising at least one radically convertible monomer in radical conditions, (a) in the presence of at least one radical initiator and a compound (I) of formula (II) wherein R to R each represent, independently of each other, hydrogen, an unsubstituted or substituted alkyl radical, cycloalkyl radical or aralkyl radical or an unsubstituted or a substituted aromatic hydrocarbon radical, on the condition that at least two of R to R represent an unsubstituted or a substituted aromatic hydrocarbon radical, in an aqueous phase
