    摘要: WHEREIN R is a -O-(lower alkyl) group of one to seven carbon atoms; p is from 1 to 6; T is a halogen, a perhaloalkyl, -NO, and -NO2; and the ratio m : n is from 0 : 1 to 50 : 1, preferrably n can be from 0.1 percent to 10 percent of the units in the polymer. The polymers are cured with such curing agents as an epoxide, a metal oxide, and chromium perfluoroacetate to produce rubbers having good physical properties and chemical resistance. Thus, liquid and solid polymers are provided as well as elastomers derived therefrom.

    OR

    A cured, nitroso polymer has been provided by curing polymers obtained by polymerizing monomers which have pendant groups convertible to pendant moieties which are crosslinkable. Some of these monomers with the crosslinkable, pendant groups cannot be introduced into the polymer directly. The polymers with the pendant groups are derived from monomers forming recurring units as represented by the general formulas:
