摘要:
This invention provides various copolymers comprising a first repeating unit of the chemical formula: ##STR1## in which R.sub.1 and/or R.sub.2 are alkyl groups and a second repeating units generally having the chemical formula: ##STR2## and combinations of two or more thereof wherein R is a hydrogen atom or a methyl group and the first repeating unit is less than 45 weight percent of the total weight of the copolymer. This invention also relates to use of these copolymers in the fabrication of absorbable surgical devices such as sutures and as coatings for medical devices. Additionally, described are blends and polyoxaesters containing the first repeating unit.
