Abstract: The invention relates to multiphasic polymers comprising from 45% to 95% by weight of a first polymer P1 and from 5% to 55% by weight of a second polymer P2, said polymers P1 and P2 being of distinct compositions, said polymer P1 being obtained by polymerization from a mixture of monomers comprising at least one anionic monomer (a) having a polymerizable vinyl group, at least one nonionic hydrophobic monomer (b) having a polymerizable vinyl group, at least one cross-linking monomer (c) and at least one associative monomer (d) having a polymerizable vinyl group and a hydrophobic hydrocarbon chain and said polymer P2 being obtained by polymerization from a mixture of monomers comprising at least one anionic monomer (a′) having a polymerizable vinyl group, at least one nonionic hydrophobic monomer (b′) having a polymerizable vinyl group and at least one cross-linking monomer (c′). It also relates to a method for the preparation of these polymers, to aqueous compositions comprising them and to their use as thickening and suspending agents.

Abstract: The present invention relates to a polymer obtained by radical polymerization of a mixture of monomers comprising: at least one anionic monomer (a) having a polymerizable vinyl function; at least one non-ionic hydrophobic monomer (b) having a polymerizable vinyl function; and one or more crosslinking monomer(s) (c) including at least one compound of formula (I) in which R is a hydrogen atom or a methyl group, n is zero or an integer from 1 to 30, and R1 is a linear or branched C1-C20 alkylene group. The present invention also relates to a process for the preparation thereof by radical polymerization, to an aqueous composition comprising same, to the use thereof as a thickener and suspending agent and also to the use of a monomer of formula (I) for synthesizing a polymer.
