More Information
Summary:Provided are polymer compositions polymer composition comprising (i) one or more multistage polymers comprising (a) a first stage polymer having a Tg of −20° C. or lower, and (b) a final stage polymer having a Tg of 50° C. or higher, (ii) one or more phosphate surfactant in an amount of 50 ppm or more, based on the dry weight of the multistage polymer, and (iii) one or more alkaline phosphate in an amount of 100 ppm or more, measured as the weight of phosphorous, based on the dry weight of the multistage polymer. Also provided are matrix resin compositions comprising such polymer compositions and a matrix resin.
