The present disclosure provides copolymers useful in medical devices. For example, the disclosure provides copolymers comprising the polymerization product ester block, ether blocks and diisocyanates. In certain embodiments, the disclosure provides a medical copolymer for implantation comprising ester blocks and ether blocks, wherein: the ester blocks comprise a negative free energy transfer and the ether blocks comprise a positive free energy transfer, the ether and ester blocks are less than 1/10 the length of said copolymer, and, the blocks are distributed such that no domain of contiguous blocks possessing the same polarity of free energy transfer are less than &#x2153; of the molecular weight of the copolymer. The disclosure further provides methods of making the aforementioned polymers, and medical devices comprising the polymers.
