    摘要： A cross-linkable polymer composition is obtained by admixing an unsaturated polymer, a polyfunctional hydrazide halide of a specified formula, and material that provides upon contact with atmospheric moisture at least one alkaline reactant that reacts with the hydrazide halide to form the corresponding polyfunctional nitrile imine which in turn cross-links the unsaturated polymer.

    摘要： A CROSS-LINKABLE POLYMER COMPOSITION IS OBTAINED BY ADMIXING AN UNSATURATED POLYMER, A POLYFUNCTIONAL HYDRAZIDE HALIDE OF A SPECIFIED FORMULA, AND MATERIAL THAT PROVIDES UPON CONTACT WITH WATER AT LEAST ONE ALKALINE REACTANT THAT REACTS WITH THE HYDRAZIDE HALIDE TO FORM THE CORRESPONDING POLYFUNCTIONAL NITRILE IMINE WHICH IN TURN CROSS-LINKS THE UNSATURATED POLYMER.

    摘要： DISCLOSED IS A SULFUR DIOXIDE ADDITION PRODUCT HAVING THE FORMULA:

    (R-C(-R)
    (-C(-R)2-C(-R)2-)).SO2

    WITH SULFUR DIOXIDE UNDER SUBSTANTIALLY ANHYDROUS CONDITIONS AND PREFERABLY IN AN INERT LIQUID IN WHICH THE COMPOUND IS SUBSTANTIALLY SOLUBLE AND THE ADDITION PRODUCT IS SUBSTANTIALLY INSOLUBLE.

    (-C(-R)2-C(-R)2-)

    (R-)2-C
    WHEREIN Z IS SELECTED FROM THE GROUP CONSISTING OF THE N AND R-C RADICALS, EACH R IS INDEPENDENTLY SELECTED FROM THE GROUP CONSISTING OF THE HYDROGEN AND C1-C8 ALKYL RADICALS N IS 1 WHEN Z IS THE R-C RADICAL AND N IS 1-2 WHEN Z IS THE N RADICAL. THIS ADDITION PRODUCT IS MADE BY CONTACTING A COMPOUND HAVING THE FORMULA:
