    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 suber-toughened multiphase thermoplastic composition is provided by incorporating an effective amount of at least one functionalized, selectively hydrogenated alkenyl arene/conjugated diene block copolymer to which has been grafted an effective amount of carboxyl functional groups primarily in the alkenyl arene blocks thereof with poly (ethylene terephthalate). The carboxyl functional groups are present as carboxylic acids and their salts in an effective salt to acid ratio for super-toughening the composition. Additionally, the block copolymer phase has an effective phase size for super-toughening the composition.

    摘要： A modified unsaturated polyester useful in preparing molded products having improved impact resistance and surface characteristics is prepared as a block copolymer comprising at least one polyester block and an elastomeric block. The modified unsaturated polyester is prepared by reacting an elastomeric polymer having at least one terminal functional group selected from the group consisting of carboxyl groups, hydroxyl groups and mixtures thereof with either a preformed unsaturated polyester, thereby producing the modified unsaturated polyester directly or with monomer useful in preparing an unsaturated polyester and thereafter growing the unsaturated polyester via condensation of additional monomer. The elastomer is, preferably, a block copolymer comprising at least one polymer block containing predominantly monoalkenyl aromatic hydrocarbon monomer and at least one polymer block containing predominantly conjugated diolefin monomer units. The modified unsaturated polyester is useful in thermosetting resin compositions.

    摘要： Completely polymerizing olefinic monomer feed, in contact with a coordination catalyst suitable for olefin polymerization, in a mold having the shape of the article, at conditions under which the polymer is produced as a coherent, useful article in the shape of the interior of the mold, and removing the article from the mold. This method permits the production of polyolefin articles which are difficult or impossible to produce from polyolefin powder or pellets by conventional methods, such as articles of polyolefins of such high molecular weight that the polymer would not be processable by a melt process; articles containing extremely high filler loading; articles containing interconnected reinforcement; and articles from molds which require substantial flows through narrow passages.
