    摘要: A biocompatible multipolymer, having a backbone comprising about 10 to 45 wt % of at least one hard segment and about 55 to 90 wt % of soft segments. The soft segments are divided into three groups, 5 to 25 wt %, of total soft segment weight, of an oxygen permeable soft segment; 5 to 25 wt %, of total soft segment weight, of a hydrophilic soft segment; and 50 to 90 wt %, of total soft segment weight, of a biostable, relatively hydrophobic soft segment.

    摘要: The present invention provides a composition that softens at a predetermined temperature, preferably between about 20.degree. C. and 90.degree. C., and more preferably between about 20.degree. C. and about 62.degree. C., comprising at least one block copolymer having at least two thermal transition temperatures. The composition is characterized by at least two thermal transition temperatures, one of which is a predetermined lower transition temperature, preferably between about 20.degree. C. to 90.degree. C., and more preferably between about 20.degree. C. to about 62.degree. C., and one of which is an upper transition temperature. The present invention also provides a method of making the composition, a method of making biomedical materials and articles, and toys and toy components, with shape-memory properties from the composition, and biomedical materials and articles, and toys and toy components, with shape-memory properties made from the composition.

    摘要: Novel linear polysiloxane-polylactone block copolymers are useful as surface modifying additives due in part to their miscibility with a wide variety of base polymers. A particularly preferred polysiloxane-polycaprolactone linear blocked copolymer is miscible with nylon and is useful for forming surface modified nylon products.

    摘要: Novel linear polysiloxane-polyacetone block copolymers are useful as surface modifying additives due in part to their miscibility with a wide variety of base polymers. A particularly preferred polysiloxane-polycaprolactone linear blocked copolymer is miscible with nylon and is useful for forming surface modified nylon products.
