Abstract: Polyesteramide (PEA) copolymers are disclosed, having structures that include repeating units that contain various monomer residues characterized herein and present in the repeating units at defined ranges of molar equivalents. These copolymers can possess a number of important advantages for providing longer performing glucose sensors and/or for simplifying their design. For example, in vivo modeling has confirmed that these polymers exhibit both decreased collagen deposition and increased neovascularization (angiogenesis). Additional testing has demonstrated favorable oxygen and glucose transport capabilities, as well as other relevant properties.

Abstract: Disclosed are polymerizable compositions, methods, and articles and coatings related to multi-polymer networks wherein at least one of the polymer networks is based on particles. In an embodiment, the polymerizable compositions comprise at least two parts: 1) a polymer forming part comprising one or more compounds comprising a polymerizable group, wherein a composition consisting of the polymer forming part, if 90% or more polymerized, has a Tg of less than 25° C. and a prescribed volume average cross-link density at 100° C.; and 2) swellable particles comprising cross-links and having a Tg of less than 25° C. and a prescribed cross-link density. The swellable particles swell to a prescribed swelling ratio by mass from their non-swollen state if the swellable particles are swollen to equilibrium in a mixture consisting of the polymer forming part and the swellable particles.
