Spherical particles, method for production of spherical particles and use thereof

摘要

Spherical particles having a mean diameter in the range from 1 to 20 μm, comprising (a) from 85 to 99% by weight of a crosslinked random copolymer having a glass transition temperature Tg in the range from −75 to −40° C. (b) and from 1 to 15% by weight of at least one organic substance selected from waxes, protective colloids and plasticizers.
