  • Patent number: 6891019
    Abstract: Anionic polymerization initiators useful in the preparation of polymers having a protected amine functional group. The amine functionality includes a first protecting group, which can be aralkyl, methyl, allyl or tertiary alkyl group. The other of the amine protecting groups can be the same as the first protecting group. Alternatively, the second protecting group can be different from the first protecting group, in which case it is selected to have differential stability to agents used to remove the aralkyl, methyl, allyl or tertiary alkyl protecting group.

  • Patent number: 6875812
    Abstract: An object of the present invention is to provide an agent serving both as a compatibilizer and an impact strength-imparting agent, which is freed from layer separation phenomenon and capable of improving compatibility to a polyphenylene ether and/or a polyolefin without detriment to weld tensile strength and low temperature impact strength. Another object is to provide a resin composition, which is obtained by blending the agent serving both as a compatibilizer and an impact strength-imparting agent with other thermoplastic resin, and which is superior in its impact resistance, particularly impact strength at low temperature, heat resistance and processability.

  • 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.
