Abstract
Modified vinyl-aromatic polymers, which are suited for being moulded or vacuum-formed and which have an improved resistance to fissuring under stress, containing from 6% to 12% by weight of an ethylenically unsaturated nitrile and having the following characteristics: a) at least 23% by weight of an elastomeric phase insoluble in toluene; b) the elastomeric phase has a swelling index in toluene greater than 10; c) a melt-index of at least 1.5; d) a bending-modulus greater than 15,000 kg/sq.cm; e) a torsional modulus greater than 5,500 kg/sq.cm; and f) an Izod resistance at 23 DEG C greater than 7 kg cm/cm. The polymers are obtained in the Examples by an inversion process, i.e. a bulk prepolymerization followed by an aqueous suspension polymerization stage. The polymers adhere well to polyurethane and are resistant to perfluorinated refrigerant fluids.
