摘要:
A copolymer for an fluorine-containing elastomer having excellent low temperature resistance and alcohol resistance comprises vinylidene fluoride units and fluorovinyl ether units having the formula CF.sub.2 =CFOX (X represents a C.sub.3 -C.sub.9 perfluoroalkyl group which has ether bond having 1-3 oxygen atom) at a molar ratio of vinylidene fluoride units to fluorovinyl ether units of 95:5 to 50:50 and at a total content of the units of at least 80 mole %.
摘要:
A fluoropolymer composition useful in the manufacture of cured fluoropolymer articles can be made by mixing a specified copolymer with an organic peroxide such as a dialkyl peroxide, and preferably also adding a divalent metal oxide and/or hydroxide and a suitable coagent such as triallyl isocyanurate. This composition contains a copolymer obtained by copolymerizing a small amount (e.g. about 0.5-3 mole %) of a bromine-containing olefin with certain fluorine-containing compounds.
摘要:
A process for producing substantially colorless poly(vinyl bromide) homopolymer and copolymer latexes at high rates and in high yields which includes adding an aqueous solution of a reducing agent to an emulsion of vinyl bromide containing a water-soluble peroxide, or adding an aqueous solution of peroxide to an emulsion of vinyl bromide containing a water-soluble reducing agent. The latexes can be dried without significant color development and the poly(vinyl bromide) homopolymers and copolymers obtained therefrom have improved color stability.
