Polymeric Biomaterials

2011
Biomaterials are an indispensable element in improving human health and quality of life. Applications of biomaterials include diagnostics (gene arrays and biosensors), medical supplies (blood bags and surgical tools), therapeutic treatments (medical implants and devices), and emerging regenerative medicine (tissue-engineered skin and cartilage ...

Polymeric surfactants in emulsion polymerization

Makromolekulare Chemie. Macromolecular Symposia, 1990
AbstractThe stabilizing efficiency of a variety of amphipathic copolymers was studied in aqueous emulsion polymerizations of styrene, methyl methacrylate and acrylonitrile. Using the number, and size of the particles as the criterion of stability, it was found that the availability for anchoring of the backbone in the amphipathic graft copolymers was ...

On the polymerization of tropomyosin

Archives of Biochemistry and Biophysics, 1962
Abstract The polymerization of tropomyosin was studied by light scattering, covering a wide range of protein and salt concentrations. Depolymerization of tropomyosin molecules with dilution was found at very dilute protein concentration, a phenomenon which had not been observed.

Polymerization of and in mesophases

Advances in Colloid and Interface Science, 2006
The use of surfactant mesophases such as vesicular and lyotropic mesophases as templates for the preparation of nanostructured polymers by polymerization is reviewed. Recent developments using polymerizable and polymeric surfactants in mesophase formation and polymerization are also represented with examples.

Polymerization of Methyl Methacrylate with the Carbon Tetrachloride/Dichlorotris- (triphenylphosphine)ruthenium(II)/Methylaluminum Bis(2,6-di-tert-butylphenoxide) Initiating System: Possibility of Living Radical Polymerization

, 1995
Introduction. Because of the virtual absence of chain transfer, termination, and other side reactions, living polymerization is among the best methods for the synthesis of polymers with controlled molecular weights and architecture^.^ It is therefore not

Organic Syntheses Using Polymeric Supports, Polymeric Reagents, and Polymeric Catalysts

Journal of Macromolecular Science, Part C: Polymer Reviews, 1976
Abstract In conventional organic syntheses, organic molecules are treated with a reagent or reagents and the transformed organic molecules, now termed the product, are isolated. The various steps in a conventional organic synthesis may be represented schematically as in Fig. 1.
