Modifying composition of powder impact, dispersion of particles of spray-drying polymer, and polymeric composition

摘要

"MODIFIING IMPACT COMPOSITION IN DUST, DISPERSION OF SPRAYABLE POLYMER PARTICLES BY SPRAYING, AND, POLYMERIC COMPOSITION". A high-grade powdered impact modifier composition is arranged, containing two or more populations of polymer particles, having a fraction by weight of total powder above 90 percent by weight. Dispersions of aqueous polymer particles intended for the preparation of these high-rubber impact modifiers that can be spray dried are also arranged. Also arranged are polymeric compositions, having a matrix resin component and impact modifiers of high powdered rubber content.
