  • Patent number: 7919562
    Abstract: The present invention relates to supramolecular polymers containing sequence-selective hydrogen bonding subunits in their backbone which form double helices. The invention allows for tuning of the numbers and sequences of donor/acceptor units incorporated in any one crosslinking hydrogen bonding subunit and hence tuning of the interaction strength not only through the amount of crosslinking material incorporated but also through modulation of the strength of the crosslinking interactions. It also allows for the incorporation of more than one type of crosslinking agent in the material allowing for multiple strengths of crosslinking which are each tunable with regard to disruption from solvent, temperature and stress. Hydrogen bond strength between oligomeric chains can be tailored through modification of the numbers and sequences of the donors/acceptors in the oligomers.

  • Patent number: 4946931
    Abstract: Polymers are provided that are useful for making biodegradable sustained release agent dispensers and which contain at least one of the following mer units (I) and (II) ##STR1## wherein X is a quadrivalent organic grouping, A and B are hydrogen or lower alkyl, and R is hydrocarbyl or oxyhydrocarbyl of 1 to 14 carbon atoms and, if oxyhydrocarbyl, containing 1 to 4 oxy groups, and may be either aliphatic or aryl, unsubstituted or substituted with one or more lower alkyl, amino, nitro or halogen moieties. Methods of synthesizing the novel polymers are also provided, as biodegradable beneficial agent dispensers prepared using the novel polymers.

  • Patent number: 4855132
    Abstract: Biodegradible polymers are provided which may contain a biologically active substance, e.g. a drug such as insulin, which is released over a period of time as the polymer erodes when in contact with a body fluid. The polymer contains an amine functionality whereby it erodes faster at low acid pH's than at higher acid pH's. As an example, the polymer may contain insulin and may contain or may have an encapsulating hydrogel containing glucose oxidase. As the blood sugar level of a diabetic person rises, e.g., after a meal, glucose diffuses into the polymer or hydrogel and is converted to gluconic acid which lowers the pH, and accelerates erosion and the release of insulin.

  • Patent number: 4789401
    Abstract: The invention concerns a collagen sponge which has a denaturation temperature of at least 37.degree. C., is not cross-linked and in one of its two embodiments forms an optically clear solution in aqueous medium. As compared with the collagen sponges previously known, it is particularly suitable as support material for pharmaceutical and cosmetic active substances since it has a higher denaturation temperature than the latter and dissolves again in contact with body fluid. The collagen sponge of the invention is prepared from an optically clear collagen solution by precipitation with neutral salts, dissolving and reprecipitation and then subjecting the collagen to freeze-drying without removal of the precipitation salt. Acid-swollen collagens and/or cellulose or cellulose derivatives can also be added to the solution, whereby the physical properties of the collagen sponge can be affected.
