    摘要: The present invention relates to a composition comprising scattering particles. In particular the present invention relates to polymeric composition comprising scattering particles for lightning applications or light guides. The invention also relates to a process for manufacturing such a polymeric composition comprising scattering particles for lightning applications or light guides. More particularly the present invention relates to a polymeric (meth) acrylic composition comprising inorganic scattering particles for lightning applications or light guides.

    摘要: Disclosed are styrenic polymers made by a mass or solution process, where the amount of trimer consisting of styrene and/or acrylonitrile is less than about 0.50 weight percent. Also disclosed is a method of minimizing the amount of trimer consisting of styrene and/or acrylonitrile in styrenic polymers made by a mass or solution process. The method includes the steps of lowering the temperature of the polymerization reaction mixture and including more than one initiator in the polymerization reaction mixture.

    摘要: 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.
