Toughening of PMMA by in‐situ polymerisation of methyl methacrylate/acrylonitrile‐butadiene rubber solutions to give blends with a multiple‐inclusion morphology has been achieved This contrasts with the lack of impact toughening observed upon direct blending of PMMA with the same rubber. The toughened blends are analogous to HIPS in terms of the multiple‐inclusion morphology and the observed cross‐linking within the separated elastomeric phase but possess significantly larger separated phase domains.
