  • Publication number: 20120190795
    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.

    Abstract: In a composite of vulcanizable rubber or rubber-like composition with one or more metal reinforcement elements embedded therein, the metal reinforcement element is coated with a polymer or non-cured rubber composition compatible with and co-polymerizable, co-vulcanizable or crosslinkable with said vulcanizable ruber composition to be reinforced, and additionally bearing functional groups either covalently bonding to the metal surface of said reinforcement element or forming covalent bonds with the outward directed first functional groups of a mono- or multimolecular layer of a bifunctional adhesion promoter intercalated between said metal and said coating and bound to said metal by its second functional groups. A cured rubber or rubber-like product, for instance a pneumatic tire, is obtained by vulcanization of such a composite.

  • Patent number: 6777499
    Abstract: The present invention relates to multiblock interpolymers having the following symmetric structures and processes for their preparation: Y-X-Y, wherein Y represents a block of a random copolymer of conjugated diene and monovinyl aromatic monomer; and X represents a block of butadiene homopolymer, a block of isoprene homopolymer, or a block of butadiene/isoprene copolymer, and processes for the preparation thereof. The present multiblock interpolymers have in the same molecule both a rubber block of random copolymer of conjugated diene and monovinyl aromatic monomer and a rubber block selected from blocks of butadiene homopolymer, isoprene homopolymer and butadiene/isoprene copolymers, and hence possess excellent properties of the both two kinds of rubbers, and can be used widely as integrated rubber materials with excellent property balance, the present processes can simply prepare the above integrated rubber material in situ in a single reactor.

  • Publication number: 20040077788
    Abstract: The present invention provides a block copolymer of styrene and an unsaturated cyclic anhydride, such as maleic anhydride, a process for making a copolymer using controlled free radical polymerization in which certain parameters are adjusted to control the microstructure and molecular weight of the copolymer, and a method for using the block copolymer, including as a compatibilizer. Microstructure and molecular weight in the block copolymer can be controlled by adjusting the ratio of stable free radical to initiator. The copolymer can be made in a one step process and has a controlled microstructure that allows one block to be reactive toward several chemical moieties available in engineering polymers and the other block to be fully miscible with polystyrene or polymers miscible with polystyrene or polymers miscible with polystyrene such as polyphenylene ether.
