Vinyl polymer for delustering the surfaces of thermoplastic masses

摘要

The invention relates to a particle-shaped polymer (P) with a particle size ranging from 0.5 to 100 mu m and a swelling index of 1 to 50 comprised as anionic polymerized components. According to the invention, at least one anionic polymerizable vinyl monomer and at least one monomer comprising at least two anionic polymerizable functional groups having the same or varying reactivity or a mixture thereof are used as cross-linking agents.
