摘要：NOVELTY - Polyester with reactive side radical function group is polymerized by monocase or copolymerized by monocase and caprolactone, lactide, or glycolide. The average molecular weight of the obtained polymer is 3000-300000. USE - For reaction with biological material for biology regulation and biology activation-modification. DETAILED DESCRIPTION - Polyester with reactive side radical function group is polymerized by monocase of formula (1) or copolymerized by (1) and caprolactone, lactide, or glycolide. The average molecular weight of the obtained polymer is 3000-300000. R=-(CH2)b(C(R1)H)cC(=O)R2 or -(CH2)b(C(R1)H)cR3; a=1, 2, or 3; b, c=0 or 1; R1=H or 1-6C alkyl; R2=OH, OR4, NH4, or NR5R6; R3=CN, NO2, NH2, or NR5R6; R4=1-6C alkyl or CH2C6H5;and R5, R6=H or 1-6C alkyl, where R5 and R6 can not be H at the same time. The weight ratio between (1) and caprolactone, lactide, or glycolide is 1:1-10.
