    Abstract: An improved amine-containing antioxidant compound for stabilizing the polymeric products of ring-opening metathesis-catalyst-polymerization of the norbornene-type monomer reactions described above, and that effectively delays degradation by olefin oxidation of physical properties as well as avoiding discoloration of such polymeric products and discoloration of surface coatings applied for aesthetic purposes, and its use as a comonomer in a ring-opening metathesis-catalyst-polymerization of a norbornene-type monomer that undergoes ring-opening polymerization in the presence of a metathesis catalyst are disclosed.

    Abstract: Disclosed is a method for treating the surface of a strained ring cycloolefin polymer article, in particular an article molded from poly(dicyclopentadiene) or a copolymer of dicyclopentadiene and another strained ring cycloolefin, comprising halogenating the surface of the article with a halogen, a pseudohalogen compound, or an interhalogen compound to improve the properties of the article, by increasing chemical resistance, improving retention of properties upon aging, reducing emission of residual monomer, and encouraging better adhesion of paint.

    Abstract: Matlack Case 30 SOLID CATALYST COMPONENT FOR OLEFIN POLYMERIZATION The transition metal component of a Ziegler-Natta catalyst is composed of a titanium halide deposited on a magnesium chloride support. The support is prepared by a process involving reaction of a magnesium alkanoate with an alkylaluminum dichloride in a hydrocarbon solvent and treatment of the magnesium chloride particles formed in the reaction with a hydrocarbon solvent and with an electron donor, preferably an aliphatic ether.
