  • Patent number: 6815498
    Abstract: A process for the preparation of a reaction product (A), which comprises the following stage (i): (i) Reaction, under free radical conditions, of a reaction mixture comprising at least one monomer (a), capable of free radical reaction in the presence of at least one free radical initiator and a compound of the formula (I)  where R1 to R4, independently of one another, are each hydrogen, an alkyl radical, cycloalkyl radical or aralkyl radical, each of which is unsubstituted or substituted, an unsubstituted or substituted aromatic hydrocarbon radical, with the proviso that at least two of the radicals R1 to R4 are an unsubstituted or substituted aromatic hydrocarbon radical, or R1 and R2 or R3 and R4, in each case in pairs, are a substituted or unsubstituted aromatic hydrocarbon having 6 to 18 carbon atoms and a functional group which, in conjugation with the C—C double bond in the formula I, has a multiple bond between a carbon atom and a heteroatom, 10% by weight or less of wate

  • Patent number: 6809165
    Abstract: 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.
