  • Publication number: 20200131294
    Abstract: A polystyrene-g-(polyisobutylene-b-polystyrene) is taught. The polystyrene-g-(polyisobutylene-b-polystyrene) is synthesized by first providing a polystyrene backbone. Once the polystyrene backbone is provided, the polystyrene backbone is acetylated to provide acetyl groups on the polystyrene backbone. Next, the acetyl groups are converted to —C(CH3)2OH groups. Finally, the living polymerization of isobutylene is initiated, which is then followed by the living block polymerization of styrene. A polymer network of polystyrene-g-(polyisobutylene-b-polystyrene)s is also provided.

  • Publication number: 20190167601
    Abstract: In one or more embodiments the present invention provides a three layer bimodal amphiphilic co-network (?-APCN) based drug delivery device and methods for its making and use. In various embodiments, the system is based on a three-layer scheme. A center layer is composed of a ?-APCN matrix containing a high drug loading and exhibiting high drug diffusivity and two outer layers which are also ?-APCN-based, contain no-drug and are instead loaded with a diffusional barrier such as vitamin E, which considerably slows drug diffusion through these outer layers. Both modeling and experimental data demonstrates that the combined effect of non-uniform distribution of drug loading and diffusion constants within the three-layer systems of various embodiments of the present invention is capable of maintaining a low local drug concentration at the polymer-fluid interface, thus achieving zero-order kinetics.

  • Patent number: 10301421
    Abstract: Sulfur containing, hydroxyl-telechelic PIBs, hydrolytically and oxidatively resistant, biocompatible and biostable polyurethanes (PUs) made therefrom, and methods for making both are disclosed. Well-defined hydroxyl telechelic PIBs are synthesized by a thiol-ene click photochemical reaction between PIBs carrying unsaturated end groups and 2-mercaptoethanol (HS—CH2CH2—OH). This regioselective process affords HO—CH2CH2—S-PIB-S—CH2CH2—OH (abbreviated herein as HO—S-PIB-S—OH) in high yield. In some embodiments, these HO—S-PIB-S—OH polymers may be reacted with diisocyanates and a chain extender to form sulfur containing PIB-based PUs. These sulfur containing PIB-based PUs have been found to have properties and chemical stability that are very similar to that of PUs made from di-hydroxyl terminated PIBs (OH-PIB-OHs) without sulfur, but have surprisingly increased creep resistance and are easier and less expensive to make.
