摘要：
The invention concerns multiphase polymers comprising 45 % to 95 % by weight of a first polymer P1 and 5 % to 55 % by weight of a second polymer P2 said polymers P1 and P2 being different compositions said polymer P1 being obtained by polymerisation from a mixture of monomers comprising at least one anionic monomer (a) having a polymerisable vinyl functional group at least one nonionic hydrophobic monomer (b) having a polymerisable vinyl functional group at least one crosslinking monomer (c) and at least one associative monomer (d) having a polymerisable vinyl functional group and a hydrophobic hydrocarbon chain and said polymer P2 being obtained by polymerisation from a mixture of monomers comprising at least one anionic monomer (a ) having a polymerisable vinyl functional group at least one nonionic hydrophobic monomer (b ) having a polymerisable vinyl functional group and at least one crosslinking monomer (c ). The invention also concerns a method for preparing said monomers aqueous compositions containing same and the use thereof as a thickening and suspending agent.
