    摘要: A hydrophilic polymer blend where at least one of the polymer materials is a water insoluble polymer and one of the materials is a hydrophilic water-soluble polymer. The invention includes a method of forming the hydrophilic polymer blend by melt mixing the hydrophilic polymer and the insoluble polymer into a finely dispersed polymer blend, forming strands of the hydrophilic polymer blend, and then pelletizing the strands.

    摘要: The present invention includes a lubricious polymer blend wherein at least one of the polymer materials is a water insoluble polymer and one of the materials is a lubricious water-soluble polymer. The invention includes a method of forming a desired medical device by melt mixing the selected polymers and then forming the polymer blend into the desired shape. The method further includes cross-linking the polymer blend after or before being shaped into the medical device in order to improve the retention of the lubricous polymer during exposure to abrasive forces or to materials which would extract the lubricious surface, such as water. Cross-linking the polymer blend may be improved by adding a cross-linking agent and/or cross-linking he polymer blend in the presence of a selected inert atmosphere.

    摘要: The present invention relates to an anti-friction and anti-wear liquid coating composition for use with parts made of materials that have softening points below about 300° F. and articles so coated. The present invention also relates to a method of coating parts made from a low softening point materials with an anti-friction and anti-wear hard coating composition. The coating composition comprises a mixture of (i) solid lubricants comprising boron nitride, graphite and molybdenum disulfide, (ii) a thermoset resin system, (iii) catalyst for curing the resin system and (iv) a solvent system comprising highly volatile solvents. The coating composition is applied to the part and cured to form a coating on the part.
