摘要：
#$%^&*AU2007202470B220120913.pdf#####ABSTRA CT There is provided a multistage polymer that comprises (a) at least one soft polymer having glass transition teiperaturc of 40C or lower, and (b) at least one hard polymer having glass transition temperaLure higher than 40C, wherein the glass transition temperature of said hard polymer is at least 10C higher than the glass transition temperature of said soft polymer, wherein the weight ratio of said hard polymer to said soft polymer is from 1.01:1 to 100:1, and wherein said multistage polymer, after exposure to liquid water followed by drying at temperatures below 100C, shows maximum thermal transition temperature in an atmosphere of 0% relative humidity that differs by 20C or less from the maximum thermal transition temperature in an atmosphere of 75% relative humidity. Also provided are an aqueous latex comprising such a multistage polymer, a composition comprising a powder comprising such a multistage polymer, a solution comprising such a multistage polymer, and a method of styling hair comprising applying such a multistage polymer to the hair.
