    Abstract: Oriented films are prepared. A thermoplastic vulcanizate, prepared by mixing at least 20 wt % of a thermoset rubber by weight of the total composition into a thermoplastic polymer are disclosed. After the mixture is prepared the thermoset rubber is entrained as discrete particles within the continuous thermoplastic polymer phase. The resulting composite is subjected to a stress either by pulling, blow molding, or any other film-forming process as is known in the art. This stress causes the continuous phase polymer molecules to become aligned or oriented in the direction in which the stress was applied, thus creating the oriented thermoplastic vulcanizate of the invention. This material has improved gas permeability and improved flexibility properties.

  • Publication number: 20030235787
    Abstract: The present invention provides a composition and a method for forming a pattern on a substrate with the composition by forming a cross-linked polymer from the composition upon exposing the same to radiation. The viscosity and wetting properties of the composition are selected to facilitate formation of a layer from a plurality of spaced-apart beads of the material disposed on the substrate. To that end, in one embodiment of the present invention the composition includes a mono-functional acrylate component, a poly-functional molecule component, and an initiator component responsive to the radiation to initiate a free radical reaction to cause the mono-functional acrylate component and the poly-functional molecule component to polymerize and crosslink.

  • Patent number: 6663962
    Abstract: For the preparation of powders formed of copolyesteramides by anionic polymerization, at least one lactam and at least one lactone are copolymerized in solution in a solvent in the presence of a catalyst and of an activator, the solvent being a solvent of the lactam and the powders being insoluble in the solvent. Preferably at least two lactams and at least one lactone are copolymerized, and the copolymerization is preferably carried out in the presence of a finely divided organic or inorganic filler. The copolymerization is preferably carried out in the presence of an N,N′-alkylenebisamide, such as ethylenebisstearamide (EBS) disclosed in EP 192 515, or generally amides of formula R1-NH—CO—R2, in which R1 can be replaced by an R3-CO—NH— or R3-O— radical and in which R1, R2 and R3 denote an aryl, alkyl or cycloalkyl radical.
