    摘要: Blends of polyarylene ether resins and anionically-polymerized monovinylidene aromatic compounds having a molecular weight distribution not greater than 1.8 are characterized by a lowered melt viscosity without significant loss in mechanical properties. The incorporation of elastomeric toughening agents does not significantly negatively affect processability or other properties of the blends.

    摘要: The specification discloses a monovinylidene aromatic polymer having a molecular weight of at least 50,000 and an extremely narrow molecular weight distribution of less than 1.5, preferably with at least 80% by weight of the polymer having a molecular weight within plus or minus 30% of the weight average molecular weight. This polymer is produced through anionic polymerization of a pure feed stock which is first cooled to a temperature at which an anionic initiator preferentially reacts with impurities present in the feed stock and initiates the polymerization reaction but does not substantially propagate styrene polymerization. The initiator is uniformly dispersed into the feed stock while maintaining it at the lower temperature and the feed stock temperature is subsequently increased to a temperature at which polymerization of the sytrene proceeds normally. The resulting polymer is especially well adapted to injection molding in that exceptional strength properties are achieved in combination with good processability, e.g., melt flow rate.

    摘要: An impact resistant polymeric composition and a process for its production. The composition comprises a rigid polymeric matrix comprising an anionically polymerized copolymer of at least one isopropenyl aromatic monomer and at least one vinyl aromatic monomer, said matrix having dispersed therein an elastomeric phase comprising at least one moderately cross-linked ungrafted rubber and at least one moderately cross-linked lightly-grafted rubber, wherein the lightly-grafted rubber has a graft-to-rubber ratio of 0.9:1 or less. The elastomeric phase is melt agglomerated to provide aggregates having particle sizes in the range from 3,000 to 100,000.

    摘要: The instant invention is the storage of Type II collagen containing tissue in carbonated water. Such Type II collagen is useful for alleviating the symptoms of arthritis in mammals as well as the treatment of arthritis in mammals. Such Type II collagen is also useful for the prevention of arthritis in mammals. The instant invention is also a method for the preparation of a nutritional supplement that includes the steps of: (a) separating water-insoluble undenatured Type II collagen containing animal tissue from animal tissue not containing Type II collagen; (b) subdividing and sterilizing said tissue under conditions which do not change the original structure of the Type II collagen to produce a subdivided and sterilized product; (c) packaging the subdivided and sterilized product in carbonated water.
