| description | There is provided a multistage polymer that comprises
(a) at least one soft polymer having glass transition temperature of 40°C or lower, and
(b) at least one hard polymer having glass transition temperature higher than 40°C, wherein the glass transition temperature of said hard polymer is at least 10°C 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 1 to 100:1, and
wherein said multistage polymer, after exposure to liquid water followed by drying at temperatures below 100°C, shows maximum thermal transition temperature in an atmosphere of 0% relative humidity that differs by 20°C 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. |
