    摘要： The invention relates to free-radical polymerization and free-radical cross-linking and more particularly provides a process of free-radical polymerization or cross-linking wherein at least one polymerizable monomer or at least one compound to be cross-linked is contacted in the presence of at least one selected organic peroxides, characterized in that the organic peroxide is prepared continuously by an ex situ process with the aid of a closed plate exchanger. In the process according to the invention, it's possible to introduce the above selected organic peroxide continuously during the polymerization or cross-linking reaction.

    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.
