  • High impact polystyrene having high modulus and resistance to environmental stress cracking
    Patent number: 10066094
    Abstract: High impact polystyrenes and related monovinyl aromatic polymers generally have either a high modulus or good resistance to environmental stress cracking. The present invention is directed at polymeric materials having both a high modulus and good resistance to environmental stress cracking thus enabling the down gauging of parts, and or the use of the materials in new applications. The invention is predicated on the use of one or more, or even all of the following features: a high molecular weight matrix polymer, reduced concentration of elastomeric polymer, or methods that result in large rubber particle size.
    Type: Grant
    Filed: August 19, 2016
    Date of Patent: September 4, 2018
    Assignee: TRINSEO EUROPE GMBH
    Inventors: Rudi Veraart, Gilbert Bouquet, Mark Georges Vreys, Ronald Van Daele, Alexander De Bokx
