  • Free flowing powder
    Patent number: 7037976
    Abstract: The present invention relates to a free flowing powder composition with a particle size at most 800 ?m comprising: (a) 100 parts by weight of one or more styrenic block copolymers, at least one of which being a block copolymer (a1) comprising at least one block S having a glass transition temperature Tg above 25° C., which contains polymerized units of a vinylaromatic monomer and at least one elastomeric block B/S having a Tg below 25° C.
    Type: Grant

  • Butadiene polymers having terminal functional groups
    Patent number: RE39559
    Abstract: Hydrogenated butadiene polymers having terminal functional groups have minimum viscosity at any molecular weight when the 1,2-addition is between 30% and 70%. Hydrogenated butadiene polymers having about two terminal hydroxyl groups per molecule have surprisingly lower viscosities at 30% to 70% 1,2-addition than similar polymers having either higher or lower amounts of 1,2-addition. The polymers are useful in making coatings, sealants, binders, and block copolymers with polyesters, polyamides, and polycarbonates.
