Item A POLYURETHANE-POLYVINYLPYRROLIDONE INTERPENETRATING POLYMER NETWORK FOR MAMMALIAN-CELL ENCAPSULATION(CURRENT SCIENCE, 1995) NAIR, PDA biocompatible and noncytotoxic interpenetrating polymer network (IPN) membrane was developed for medical applications. The biostable membranes developed could also support the growth and adhesion of mice L929 fibroblast cells. This membrane could, therefore, serve as a candidate material for mammalian cell encapsulation.Item A SIMPLE METHOD FOR REMOVAL OF OLIGOMERS IN POLY(ETHYLENE-TEREPHTHALATE) FOR BIOMEDICAL APPLICATIONS(ACTA POLYMERICA, 1987) NAIR, PD; SREENIVASAN, KItem AGING OF RADIATION-STERILIZED POLYPROPYLENE - CHANGES IN SEMICRYSTALLINITY(BIOMATERIALS, 1989)Item MECHANICAL-PROPERTIES OF POLYURETHANE-POLY(ACRYLAMIDE) INTERPENETRATING NETWORKS(ACTA POLYMERICA, 1991) NAIR, PD; JAYABALAN, M; MURTHY, VNKItem MULTIPLE GAMMA-RADIATION STERILIZATION OF POLYESTER FIBERS(BIOMATERIALS, 1988)Item POLYURETHANE-POLYACRYLAMIDE IPNS .1. SYNTHESIS AND CHARACTERIZATION(JOURNAL OF POLYMER SCIENCE PART A-POLYMER CHEMISTRY, 1990) NAIR, PD; JAYABALAN, M; KRISHNAMURTHY, VNItem SOLVENT INDUCED CHANGES IN THE THERMAL-STABILITY OF A POLYURETHANE(ACTA POLYMERICA, 1991) NAIR, PDItem STUDIES ON THE EFFECT OF DEGREE OF HYDROPHILICITY ON TISSUE-RESPONSE OF POLYURETHANE INTERPENETRATING POLYMER NETWORKS(BIOMATERIALS, 1992)Interpenetrating polymer networks of polyurethane and vinyl monomers such as polyacrylamide, polyvinyl pyrrolidone, poly(hydroxyethyl methacrylate) and poly(methyl methacrylate) were implanted intramuscularly in rabbits. Attempts were made to correlate the morphological aspects of the interpenetrating polymer networks to their histological response. A relatively increased hydrophillicity of hydrophobicity of the interpenetrating polymer networks as in the case of polyurethane-polyvinyl pyrrolidone and polyurethane-poly(methyl methacrylate) interpenetrating polymer networks, respectively, could elicit an inert response whilst degradation of materials promoted reactivity.Item THERMAL-ANALYSIS OF USED AND RADIATION TREATED POLYCARBONATE (L-MW) BIOMATERIAL(BULLETIN OF MATERIALS SCIENCE, 1988) JAYABALAN, M; SREENIVASAN, K; NAIR, PD; JALAJAMANI, KN
