ABSTRACT:
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, R2and R3independently represents a hydrogen atom or a —CH2R4group, and each R4independently represents a hydroxyl group or a —OR5group (wherein R5represents a group selected from the group consisting of a C1-C10aliphatic hydrocarbyl group, a C6-C10aryl group, a —R6COOH group and a derivative thereof, and a —CH2—O—CH2—CH(OH)—CH2—OR7group, wherein R6represents a C1-C10aliphatic hydrocarbylene group and R7represents a C1-C10aliphatic hydrocarbyl group or a C6-C10aryl group), provided that all of R1, R2, and R3are not simultaneously hydrogen atoms; and 10≦x≦10,000 and 0≦y≦10,000.
