摘要: Disclosed herein are novel amorphous tetrafluoroethylene-hexafluoropropylene (TFE-HFP) dipolymers, and other copolymers containing TFE, HFP and a third monomer, many of which are more random than previous amorphous TFE-HFP copolymers, as well as a novel high productivity continuous process for making these polymers. The polymers are particularly useful in the form of coatings, films and encapsulants.

摘要: A composition and method for preparing it is disclosed. The composition in a blend of a cured fluoroelastomer which except for the cure sites is a perfluorocarbon and a thermoplastic copolymer of tetrafluoroethylene which is present as generally spherical particles having a particle size of less than 10 microns. The composition is prepared by blending the fluoroelastomer and thermoplastic copolymer at a temperature above the melting point of the thermoplastic copolymer followed by curing the fluoroelastomer.

摘要: Copolymers of tetrafluoroethylene (TFE) and hexafluoropropylene (HFP) having high HFP content and end-of-melting temperature, T.sub.m (end), as low as 200.degree. C. are disclosed. Exceptional performance as a processing aid in polyolefins results from having T.sub.m (end) of the TFE/HFP copolymer close to the processing temperature of the polyolefin. These TFE/HFP copolymers are soluble in fluorinated cyclic solvents. Copolymer/solvent systems copolymer at significant concentrations in selected solvents are fluid and stable at room temperature.

摘要: Blends of elastomers of chlorinated or chlorosulfonated polyethylene and ultra high molecular weight, i.e. at least one million, when cured with conventional curing systems for the chlorinated or chlorosulfonated polyethylene have higher tear strengths at temperatures of about 150.degree. C. than do the unblended elastomers. The amount of polyethylene in the blend is 5 to 50 parts by weight per 100 parts by weight of elastomer. The blend, thus produced has a modulus (M.sub.100) of greater than 1000 psi prior to curing.
