Hermoplastic molding material of improved toughness
Abstract
Abstract A thermoplastic molding material containing (based on the sum of A+B+C) A: from 1 to 30% by weight of one or more elastomeric polymers A having a mean particles size of from 30 to 1000 nm and comprising, based on A, A1: from 50 to 99.9% by weight of one or more alkyl acrylates A1 having from 1 to 8 carbon atoms in the alkyl radical, A2: from 0.1 to 5% by weight of one or more polyfunctional, crosslinking monomers A2 and A3: up to 50% by weight of one or more monoethylenically unsatuated monomers A3, as the graft base, B: from 5 to 40% by weight of shells B grafted onto the elastomeric polymer A and comprising, based on B, B1: from 30 to 90% by weight of one or more vinylaromatic monomers B1, B2: from 5 to 40% by weight of one or more polar, copolymerizable, ethylenically unsaturated monomers B2, and B3: from 5 to 30% by weight of one or more alkyl acrylates B3 having from 7 to 20 carbon atoms in the alkyl radical, and C: from 30 to 94% by weight of a copolymer C comprising C1: one or more vinyl-aromatic monomers C1 and C2: one or more polar, copolymerizable, ethylenically unsaturated monomers C2.
