Abstract: Ski boots and other cold weather articles are described made from polymer compositions that are exceptionally stable at low temperatures. The polymer composition, for instance, may contain a thermoplastic polymer, a thermoplastic elastomer, an impact modifier and a wear resistant additive. In one embodiment, various polymer components are selected such that they do not undergo a second order transition within a temperature range of from about 50° C. to about ?40° C., and particularly from about 23° C. to about ?40° C. In one embodiment, the polymer compositions are used to mold the outer shell of a snow ski boot.

Abstract: Fluid-assisted injection molding articles and processes for producing the articles are described. In one embodiment, a fluid-assisted injection molded article is formed from a polymeric composition containing a polyethylene terephthalate homopolymer in combination with a polyethylene terephthalate copolymer. The polyethylene terephthalate copolymer may comprise a copolymer of polyethylene terephthalate with isophthalic acid. The polymeric composition can also contain a reinforcing agent, such as glass fibers. Products made in accordance with the present disclosure have shown dramatically improved surface characteristics. In particular, pitting on the surface of the molded article is minimized.

Abstract: A polymer composition is disclosed that contains a thermoplastic elastomer combined with an ?-olefin and vinyl acetate copolymer. In one embodiment, the composition contains a thermoplastic polyester elastomer combined with an ethylene and vinyl acetate copolymer. Various synergistic effects may be realized by combining the two polymers together. In particular, a resulting polymer mixture can be produced that has many of the properties of the thermoplastic elastomer and also has controlled melt flow properties. In addition, the polymer composition may have improved and controllable mechanical and thermal properties and color stability. The polymer composition may be processed using injection molding, blow molding, or extrusion and may undergo secondary processing.
