    摘要: Solid copolymers of butene-1 and 4-vinylcyclohexene prepared by copolymerizing the monomers in the presence of a titanium halide coordination catalyst have an unobvious balance of properties including a broader molecular weight distribution, shorter crystallization half-time, greater isotacticity and greater crystallinity than butene-1 homopolymers prepared with identical catalysts.

    摘要: Disclosed is a process for preparing polymers and copolymer blocks of conjugated dienes with varying amounts of branching comprising the use of a microstructure control agent and a microstructure control agent deactivant. The polymerization can be started with or without a microstructure control agent. At some point in the polymerization prior to the completion of the addition of the conjugated diene to the polymer, the microstructure control agent can be deactivated, either partially or completely, resulting in a polymer or copolymer block having a region of less branching adjacent to a region of more branching. Preferred microstructure control agent deactivants are metal alkyls such as triethyl aluminum.

    摘要: Disclosed is a novel tetrablock copolymer having the general configuration of A1-B1-A2-B2, where the A1 and A2 blocks are mono alkenyl arene and the B1 and B2 blocks are blocks of hydrogenated butadiene, having a 1,2-vinyl content of between 25% and 60%. The blocks have well defined molecular weight ranges, resulting in a polymer having a unique set of property advantages. Also disclosed are elastomeric compositions containing the linear hydrogenated block copolymer, a styrene polymer, an ethylene polymer and a tackifying resin. These elastomeric compositions have particular utility in injection molded parts and in extruded parts such as extruded films and fibers.

    摘要: A super-tough polymeric composition comprising an engineering thermoplastic and a modified radial polymer. The engineering thermoplastic is selected from the group consisting of polyamides, thermoplastic polyesters, polyphenylene ether resins, polyarylene sulfide resins, polysulfone and the like. The modified radial polymer is modified by grafting a compound containing a carboxylic acid or carboxylic acid derivative group. The modified, radial polymer has from about 3 to about 50 arms, as determined using light scattering techniques and the arms will be olefin polymers. The polymer compositions will yield shaped articles which fail ductilely when tested using ASTM procedure D-256 at room temperature and some at -20.degree. F.

    摘要: Novel metallated polyolefins are produced by contacting a polyolefin having a vinylidene group in the terminal portion with organoalkali metal compound in the presence of alkali metal t-alkoxide or tertiary amine. The metallated polyolefin is used to initiate the polymerization of polymerizable monomers to produce block copolymers of at least two blocks, at least one of which is saturated polyolefin.

    摘要: A salt of a fatty acid is provided as a plasticizer for functionalized block copolymers of vinyl aromatics and conjugated diolefins wherein the functionalization comprises salt functionality. When this functionalized block copolymer is plasticized with the salt of a fatty acid the resulting composition will have higher tensile strengths than the raw polymer at and below the melting point of the additive and will have improved processability.
