Abstract: Replacement of the amorphous peptide domain of a structural biopolymer, such as silk from silkworms or spiders, with a nonpeptide segment while maintaining the ?-sheet forming crystalline segments provides synthetic multiblock copolymers having solid-state structures and mechanical properties similar to the naturally occurring structural biopolymer is described herein. Such synthetic multiblock copolymers may be produced as films or fibers.

Abstract: Solution blending of masterbatch of cationically functionalized polyvinyl acetate copolymer/silicate nanocomposite where the silicate is substantially exfoliated, and ethylene-vinyl acetate copolymer (EVA), produces product of increased tensile strength and Young's Modulus compared to neat EVA and reduced flammability compared to neat EVA. The product can be injection molded or compression molded or extruded without loss of these advantages.

Abstract: Silicate anchored multifunctional initiator has moiety initiating ring opening living polymerization of lactone or ethylene oxide or cyclic siloxane monomer and other moiety for initiating living free radical polymerization of ethylenically unsaturated monomer. The monomers are reacted with the initiator in a one-pot, one-step reaction to cause living polymerization of both monomers and exfoliation of silicate layers to provide dispersed block copolymer silicate nanocomposite, with the junction of the two blocks being anchored to silicate layer and each block dangling therefrom.

Abstract: Photoinitiator modified silicate and ethylenically unsaturated monomer are reacted in solvent to cause living polymerization of monomer and exfoliation of silicate layers and cause attachment of silicate layers to polymer chains, thereby providing dispersed homopolymer or block copolymer silicate nanocomposites.

Abstract: Free radical living polymerization attached nanocluster (metal oxide, e.g., gamma-Fe2O3 or FeO nanocluster or quantum dot (e.g., CdSe) nanocluster, are used for polymerization of polymer or copolymer to provide nanocomposite polymers or copolymer arms around nanoclusters.

Abstract: Nanocomposites of silicate layers or inorganic nanoparticles dispersed in a polymer or copolymer matrix are prepared by solution blending or melt blending the polymer or copolymer with nanoadditive containing from 20 to 50 weight percent silicate layers or inorganic nanoparticles dispersed in a different polymer or copolymer of Mn ranging form 10,000 to 40,000.

Abstract: Polyurethane surfaces are made more biocompatible, particularly with blood, by treatment with a block copolymer of a fluorinated oxazoline and either 2-methyl- or 2-ethyl-2-oxazoline. Such polyurethanes are useful as vascular graft or artificial heart parts.

Abstract: Excellent resolution and sensitivity in the patterning of resists utilized in device and mask manufacture is obtained with a specific composition. In particular this composition involves polymers having recurring pendant acid labile .alpha.-alkoxyalkyl carboxylic acid ester moieties in the presence of an acid generator activated by actinic radiation such as UV-visible, deep ultraviolet, e-beam and x-ray radiation.
