    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.

    摘要： A thermoplastic polymer which possesses excellent mechanical properties at both room and elevated temperatures is obtained by reacting an acyl sulfate with a block copolymer composed of at least one conjugated diene block and one alkenyl arene block. The block copolymer is first selectively hydrogenated and thereafter modified by grafting sulfonic acid functional groups primarily in the alkenyl arene blocks. The mechanical properties may be varied and controlled by varying the degree of functionalization (amount of sulfonation), and the degree of neutralization of the sulfonic acid groups to metal sulfonate salts.
