Polymer blends.

摘要

Polymer blends comprising 55 to 95 weight % acrylic vinyl aromatic matrix polymers and 5 to 45 weight % of certain core-shell polymers of less than 400 nanometer average particle diameter and with a core derived from crosslinked conjugated diolegin, vinyl and polyvinyl monomers having a toluene swell ratio of 7 to 35, and a shell containing units of vinyl aromatic monomer may provide good impact strength and clarity properties.
