Abstract

See full text

The impact-resistant thermoplastic compositions comprising (A) a rigid thermoplastic methacrylic polymer or copolymer matrix P containing mostly methyl methacrylate units, (B) at least one impact-modifying additive and (C) at least one elastomer copolymer which contains grafting sites, at least on pendant chains, and is obtained from at least one vinylaromatic monomer (C1) and from at one monomer chosen from the monomers (C2): C1-C15 linear or branched alkyl acrylates, C1-C4 alkoxyalkyl acrylates and aralkyl acrylates, dienes (C3) and ethylenically unsaturated monomers (C4) having one or more pendant initiating functional groups, the said copolymer (C) being grafted by thermoplastic polymer groups P and being dispersed in the matrix (A) in the form of nodules, which can be called 'particles', from 10 nm to 500 nm in size and able to have a droplet, capsule-type monoinclusion and/or salami-type multi-inclusion morphology.
