Abstract
The present invention generally relates to a transient copolymer that can undergo chemical or biological decomposition over a predetermined period. More specifically, the present invention relates to a transient copolymer, and preparation methods thereof, comprising at least two different macromers, wherein a first macromer is a polyester; wherein a second macromer is a condensation polymer; and wherein the molar ratio of the first macromer to the second macromer is more than 4:1. The present invention further relates to an article comprising the transient copolymer and the use of a transient copolymer for preparing an article.
Claims20
A transient copolymer comprising at least two different macromers:
- i. wherein a first macromer is a polyester selected from polyethylene terephthalate, polytrimethylene terephthalate, polyethylene furanoate, polybutylene terephthalate, polybutylene succinate, polybutylene adipate terephthalate, poly(butylene succinate-co-adipate), polyethylene succinate, polybutylene adipate, and mixtures thereof;
- ii. wherein a second macromer is a condensation polymer prepared by polymerizing one or more monomers selected from aliphatic diols, aliphatic diamines, aliphatic dicarboxylic acids, aliphatic hydroxy acids, aliphatic amino acids and/or acetylated modifications thereof;
- and
- iii. wherein the molar ratio of the first macromer to the second macromer is more than 4:1.
