  • Patent number: 10968303
    Abstract: In various embodiments, the present invention provides a strong, synthetic elastomer materials (and related methods for making same) with mechanical properties that are controlled by the stereochemically-defined double bonds within their backbone, yet have physical properties that are derived from monomer selection and defined, modifiable, chain end groups. The use of the organocatalyzed, stereospecific addition of thiols to activated alkynes, affords isolated high molar mass materials (>100 kDa) via step-growth polymerization with high levels of cis- or trans-double bond content. Furthermore, in various aspects of the present invention, it has been found that changing the monomer composition and chain end groups provides additional control over the materials' physical properties to provide more efficient compounding with polar additives. Using this approach to elastomer synthesis, further end group modification and toughening through various vulcanization strategies are also possible.

  • Publication number: 20130323291
    Abstract: A hydrophilic copolymer is designed and synthesized by copolymerization of an acidic monomer and a second hydrophilic monomer. The copolymer is non-thrombogenic, hydrophilic and incorporates reactive functional groups. The copolymer can then be covalently attached to a primer/base coat through its functional groups, to form a durable lubricious coating on medical devices. A coating formed of the polymer on a surface is non-thrombogenic and non-cytotoxic. The coating shows good stability in gamma ray, e-beam and ethylene oxide sterilization.
