Polymerisable substance with connected nanoparticles

摘要

Polymerizable mass comprises (a) acrylate and/or methacrylate with a glass transitional temperature of 0[deg] C; 0.5-70 wt.% of silicon dioxide particle with an average particle size of 1-150 nm, where the polymerizable groups are on the surface of the particle; and (c) 2 wt.% of crosslinking molecule. Independent claims are included for: (1) a polymer material obtained by hardening the polymerizable mass; and (2) an impact modifier for polymer comprising a core-shell-particle, where: the core exhibits the hardened polymerizable mass, the shell exhibits a core grafted acrylate- and/or methacrylate shell, which is preferably free of silicon dioxide particles and the shell preferably contains PMMA.
