Abstract: A biodegradable polymeric hydrogel composition including a component A and component B forming a ?-aminoester linkage such that the linkage results in gelation, wherein component A is water soluble polymer containing acrylate functionality and component B is a water soluble amine functionality useful for medical applications such as such as drug delivery, tissue engineering, and biomaterials and method of preparation thereof.

Abstract: A graft copolymer with pH dependent behavior of formula 1 Comprises, (i) a backbone having the formula 1 [A(X)B(Y)C(z)] wherein (A) is diol, (B) is dicarboxylic acid or acid anhydride and (C) is monomer containing pendent unsaturation such that (x)=41-45%, (y)=49-53% (z)=4-7% by mole; and (ii) a graft which is a polymer of the basic monomer (D) which comprises “w” weight percent of the total weight of said graft copolymer such that ‘w’ is 22-52%. The graft copolymers do not swell/dissolve at neutral and basic pH and swell/dissolve at acidic pH. The polymers are useful as protective coating for pharmaceutical dosage forms and as excipient in the development of extended release drug delivery systems.

Abstract: A pulsatile release composition which releases the content rapidly after a predetermined lag time comprising a drug containing a core, coated with a pH sensitive graft copolymer. The coating suppresses the drug release at acidic pH prevalent in the stomach and releases it either immediately or after a lag time in the intestinal region. Combinations of multiple numbers of coated and uncoated units provide a sequential pulsatile release of same or different therapeutic agents.

Abstract: This invention provides a water-soluble macromonomer having terminal unsaturation obtained by polymerization of monomers in the presence of inclusion complex of chain transfer agent in aqueous system. Hydrophobic chain transfer agent AMSD forms an inclusion complex with methylated cyclodextrin. The complexation enhances its solubility in water and enables the polymerization of water-soluble monomers in aqueous medium. After polymerization cyclodextrin is removed and the macromer with terminal unsaturation obtained can be used further for copolymerization with any vinyl monomer.

Abstract: The present invention describes water-soluble homopolymers obtained by polymerization of monomers containing multiple unsaturations. These monomers form inclusion complexes with cyclodextrins and methylated cyclodextrins. The unsaturated site involved in the formation of the inclusion complex does not take part in the polymerization reaction. After cyclodextrin is recovered, the polymer containing multiple unsaturations can be further polymerized either by thermal and/or photochemical initiators to yield crosslinked polymers.
