Abstract:
A fluoroelastomer comprising a copolymer of fluoroolefin monomers selected from one or more of the group consisting of 2,3,3,3-tetrafluoropropene, 1,3,3,3-tetrafluoropropene and 1-chloro-3,3,3-trifluoropropene, and ethylenically unsaturated co-monomers; wherein the fluoroelastomer has a glass transition temperature (Tg) of from about −60° C. to about 53° C. A process of making the fluoroelastomer.
Abstract:
Monomers, polymers and copolymers are provided that incorporate at least one naturally occurring phenolic compound, such as a plant phenol, as well as methods for producing the monomers and polymers. Plant phenols possessing a reactive group in addition to the phenolic group, such as a double bond, aldehyde, ester, alcohol or carboxylic acid, are particularly useful. Plant phenols can be isolated from a plant material, or chemically or enzymatically synthesized.

There is provided a composition containing one or more basic compounds selected from the group consisting of tertiary amines, nitrogen-containing heterocyclic aromatic compounds, alkali metal carbonate salts, alkaline earth metal carbonate salts and alkali metal hydrogencarbonate salts, and a homoallyl halide.
Abstract:
Allyl halide-halohydrinamine copolymers may be produced by mixing an allyl halide and an amine compound with an oxidated silicon compound and then by adding a halohydrin while agitating for 10 to 60 minutes.
