ABSTRACT:
Moulded articles of uniform wall thickness are prepared by vacuum-forming or thermoforming a composition comprising a uniform blend of, as base resin, a moulding grade resin having a continuous phase of a first copolymer of a styrenic monomer and an ethylenically unsaturated nitrile and a minor proportion of, as additive resin, a second copolymer of a styrenic monomer and an ethylenically unsaturated nitrile having an ultra high molecular weight, the forming operation being carried out at least 50.degree. C. above the glass transition temperature of the base resin and at a stress level of at most 1 MPa.
