Catheter tubing comprises: an elongate body comprising a base thermoplastic polyurethane; and a compounded thermoplastic polyurethane co-extruded with the base thermoplastic polyurethane to provide a section of catheter tubing discrete from the elongate body, the compounded thermoplastic polyurethane comprising a thermoplastic polyurethane and a radiopaque material, wherein the catheter tubing comprises a first elastic modulus under first conditions prior to entry into a patient; and wherein when exposed to second conditions comprising two or more in vivo stimuli for a duration of time the catheter tubing comprises a second elastic modulus that is not more than fifty percent of the first modulus.

A polymer resin composition is disclosed including a chemically attached lubricant structure to produce a self-lubricating medical device thereby eliminating the need of a secondary lubrication step currently required which is useful in medical and surgical devices.

Self-lubricating polymer composition

This disclosure relates to flame retardants that are useful for epoxy resin systems. Coating compositions and methods are provided the include an epoxy resin and a phosphate-containing flame retardant wherein the phosphate-containing flame retardant is selected from Group 1 metallic salts of a phosphate of a saccharide, Group 2 salts of a glycerophosphate, and Group 1 metallic salts of a polyphosphate. The provided flame retardants have low toxicity and are friendly to the environment.

A phosphorus-containing silsesquioxane is represented by the formula[RSiO][RSiO][RSiO][(RO)PO(CH)SiO]wherein each of R, R, R, and Rindependently represents a hydrocarbyl group; x represents an integer of from 1 to 8; m is a positive number less than 1.5; n and q are positive numbers greater than 0 and less than 1; and p is a number greater than or equal to 0 and less than 1. Further, (n+p)/q is in a range of from 0.5 to 99, and (n+p+q)=1. Curable and cured compositions comprising the phosphorus-containing silsesquioxane are disclosed.
