  • Method of making a branched polymer, a branched polymer and uses of such a polymer
    Patent number: 10711073
    Abstract: A method of making a branched polymer comprising (C?C)—(C?C)—CO groups is provided. The method comprises: (i) Providing, in admixture, at least one monofunctional monomer comprising one polymerisable carbon-carbon double bond per monomer, at least one multifunctional monomer comprising at least two polymerisable carbon-carbon double bonds per monomer, at least one chain transfer agent comprising a carbonyl group; (ii) Forming a polymer from the mixture; and (iii) Hydrolysing the polymer. A branched polymer is further provided.
    Type: Grant

  • Secondary suspending agent for suspension polymerisation reaction
    Patent number: 10106635
    Abstract: Use of a polymer as a secondary suspending agent in a suspension polymerization reaction is provided. The polymer comprising (i) residues of at least one ester-containing monomer, the ester-containing monomer (s) comprising one polymerizable carbon-carbon double bond per monomer and an ester group, and (ii) residues of at least one monomer comprising a sulfonate, sulfonic acid, sulfonic ester, sulfonamide or sulfonyl halide group the monomer (s) comprising a sulfonate, sulfonic acid, sulfonic ester group, sulfonamide or sulfonyl halide group comprising one polymerizable carbon-carbon double bond per monomer and a sulfonate, sulfonic acid, sulfonic ester, sulfonamide or sulfonyl halide group, the polymer optionally being partially hydrolyzed such that a proportion of said ester groups form alcohol groups, the degree of hydrolysis of the polymer being from 0 to 30 mol %.
