| 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): n nwherein each of R 1 , R 2 and R 3 independently represents a hydrogen atom or a —CH 2 R 4 group, and each R 4 independently represents a hydroxyl group or a —OR 5 group (wherein R 5 represents a group selected from the group consisting of a C 1 -C 10 aliphatic hydrocarbyl group, a C 6 -C 10 aryl group, a —R 6 COOH group and a derivative thereof, and a —CH 2 —O—CH 2 —CH(OH)—CH 2 —OR 7 group, wherein R 6 represents a C 1 -C 10 aliphatic hydrocarbylene group and R 7 represents a C 1 -C 10 aliphatic hydrocarbyl group or a C 6 -C 10 aryl group), provided that all of R 1 , R 2 , and R 3 are not simultaneously hydrogen atoms; and 10≦x≦10,000 and 0≦y≦10,000. |
