International Classification:
B32B 27/00
US Classification:
428421, 524 98, 524195, 524544, 524545, 524546, 526245, 526247, 526249, 526254, 526255, 252 629 PZ, 25251934, 25252021
Abstract:
Chain end functionalized fluoropolymers are disclosed exhibiting good chemical reactivity high breakdown electric field (E>100 MV/m) and high dielectric constants (i. e. , ∈>10). The polymers can be prepared by functional initiators and from a variety of fluoromonomers including vinylidene difluoride together with one or more additional monomers. The polymers can be combined with other dielectric materials to form composites having uniform composition and morphology.
Light Scattering Methods And Systems Using Supercritical Fluid Solvents To Measure Polymer Molecular Weight And Molecular Weight Distribution
View pageUS Patent:
20090046274, Feb 19, 2009
Filed:
Jul 22, 2008
Appl. No.:
12/177572
Inventors:
Mark A. McHugh - Richmond VA, US
Andrei F. Kostko - Richmond VA, US
Koji Kigawa - Rye NY, US
Katsuyoshi Kubo - Osaka, JP

International Classification:
G01N 21/00
US Classification:
356 72
Abstract:
Light scattering processes are employed to measure molecular weight and related characteristics of polymeric materials, including without limitation refractory fluoropolymers. The processes utilize a pressurized cell and a fluid under pressure to solubilize the polymeric materials and to enable light scattering measurements to be performed.
