Body fluid compatible and biocompatible resin

摘要

A body fluid compatible and biocompatible resin for use in a medical treatment involving a contact of said resin with at least one member selected from the group consisting of a body fluid and a biological tissue, which comprises at least one substituted oxyalkylene polymer having a weight average molecular weight of from 1,000 to 1,000,000 and represented by the following formula (1): wherein each of R¹, R² and R³ independently represents a hydrogen atom or a -CH₂R⁴ group, and each R⁴ independently represents a hydroxyl group or a -OR⁵ group (wherein R⁵ represents a group selected from the group consisting of a C₁-C₁₀ aliphatic hydrocarbyl group, a C₆-C₁₀ aryl group, a -R⁶COOH group and a derivative thereof, and a -CH₂-O-CH₂-CH(OH)-CH₂-OR⁷ group, wherein R⁶ represents a C₁-C₁₀ aliphatic hydrocarbylene group and R⁷ represents a C₁-C₁₀ aliphatic hydrocarbyl group or a C₆-C₁₀ aryl group), provided that all of R¹, R², and R³ are not simultaneously hydrogen atoms; and 10<=x<=10,000 and 0<=y<=10,000.
