Multiblock Copolymers Having Improved Mechanical Properties
US Patent:
7417112, Aug 26, 2008
Filed:
Apr 25, 2005
Appl. No.:
11/113494
Inventors:
Osman Rathore - Jacksonville FL, US
Dotsevi Y. Sogah - Ithaca NY, US
Dotsevi Y. Sogah - Ithaca NY, US
Assignee:
Cornell Research Foundation, Inc. - Ithaca NY
International Classification:
C07K 14/00
US Classification:
530300
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 β-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:
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.
One-Pot, One-Step In Situ Living Polymerization From Silicate Anchored Multifunctional Initiator
US Patent:
7902321, Mar 8, 2011
Filed:

Appl. No.:
11/665157
Inventors:
Dotsevi Y. Sogah - Ithaca NY, US

C08K 3/20
C08G 63/48
C08G 63/91
US Classification:
528354, 546232
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:
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.
