    摘要： The invention relates to a process comprising a stage of polymerization or copolymerization of at least one polymerizable or copolymerizable monomer by a radical mechanism in the presence of a stable free radical and of an initiator of formula: R1—O—O—R2 wherein R1 and R2, which can be identical or different, represent an alkyl, aryl, alkylaryl or aralkyl radical comprising, for example, from 1 to 20 carbon atoms. The process is fast, allows the initiator to act more efficiently and results in polymers or copolymers exhibiting a low yellowing index.

    摘要： This invention relates to copolymers of molecular mass of between 5,000 and 300,000, consisting of a hydrophilic central portion, for example a polyacrylamide chain, and of hydrophobic ends the hydrophobicity of which is comparable with that of alkyl groups containing 4-20 carbons. They are produced by polymerization of hydrophilic monomers with the aid of initiators, for example of azo type, the hydrophobic residues of which will constitute the hydrophobic ends of the final copolymer. These copolymers are useful for rheological control of aqueous and/or pigmented compositions, like paints.
