    Abstract: Provided is a low-cost, highly active, environmentally friendly living radical polymerization catalyst which does not require a radical initiator. An organic compound having an oxidation-reduction capability is used as a catalyst. Even if a radical initiator is not used, a monomer can be subjected to a radical polymerization to obtain a polymer having narrow molecular weight distribution. The cost of the living radical polymerization can be remarkably reduced. It is made possible to prevent adverse effects of using a radical initiator. The present invention is significantly more environmentally friendly and economically excellent than conventional living radical polymerization methods, due to advantages of the catalyst such as low toxicity of the catalyst, low amount of the catalyst necessary, high solubility of the catalyst, mild reaction conditions, and no coloration/no odor (which do not require a post-treatment for a molded article), etc.

  • Patent number: 8030411
    Abstract: Embodiments of the disclosed polymer composition comprise a first unsaturated polymer or polymer precursor, and an effective amount of a peptizer. The peptizer typically comprises a heteroaryl or a heterocyclic compound, other than morpholine as disclosed in assignee's prior applications. Disclosed polymer compositions are useful for making sports equipment, such as at least one layer of a golf ball, often a core. Because the compositions are useful for making golf balls, materials commonly known for making such golf balls can be used in combination with the polymer composition. A method for forming a golf ball also is disclosed. The method comprises providing disclosed compositions and then forming at least one component of a golf using the composition.

  • Patent number: 7834081
    Abstract: The present invention relates to the use of poly acrylic and/or methacrylic macroinitiators in the free radical addition reaction of vinyl aromatic monomers to improve the properties of the resulting copolymer and/or composite. More particularly, the present invention relates to the production of poly acrylic and/or poly methacrylic macroinitiators having nitroxyl end groups. Using such macroinitiators in the free radical addition reaction of vinyl aromatics such as polystyrene compatibilizes the acrylic monomer in the vinyl aromatic matrix thereby improving the properties of the resulting polymer.

  • Patent number: 7776963
    Abstract: Adhesive formulations having acrylate monomer or methacrylate monomer, or mixtures thereof, and having a reducing agent and an initiator (e.g., peroxide). The formulations may include a chelating agent solution to improve storage stability and other properties. Further, the mole ratio of the initiator to the reducing agent may be adjusted to control weight loss of the adhesives during cure. Polyvinyl acetate or its derivatives may also be employed in the adhesive formulations to reduce weight loss during cure. Moreover, certain embodiments of the formulations include a toughening-agent copolymer having a glass transition temperature (of at least one domain) that is lower than ?50° C. (?58° F.). These toughening-agent copolymers may be added to the adhesive formulations to improve impact strength and other properties of the cured adhesives at lower temperatures, e.g., ?40° C. (?40° F.), while maintaining performance of the cured adhesives at higher temperatures, e.g., 82° C. (180° F.).

  • Patent number: 7655725
    Abstract: This invention relates to a process for the preparation of a hydrogenated polymer comprising the steps of hydrogenation of at least one carbon-carbon double bond of an unsaturated polymer in latex in the presence of hydrazine, an oxidizing compound and a catalyst, followed by separation of the hydrogenated polymer from the latex. After the separation of the hydrogenerated polymer from the latex a mixing step is carried out in which the hydrogenated polymer is first mixed with an amine group containing compound and next the hydrogenated polymer is mixed with a compound that is capable of reacting with an amine. The invention also relates to the hydrogenated polymer. The invention further relates to the use of this polymer in a compounds to make an article by shaping and vulcanisation.
