The invention concerns a process for the polymerization of vinyl chloride monomer (VCM) using as initiator a diester of monoperoxyoxalic acid. The initiators are highly active and the process provides a method for the efficient polymerization of VCM at lower temperatures and/or for shorter reaction times than can be achieved with the current commercially available catalysts.

Process for polymerization using monoperoxyoxalic acid diesters

The invention concerns novel compounds of the formula I ##STR1## The compounds are herbicides and in further embodiments the invention provides processes for the preparation of compounds of formula I, intermediates useful in the preparation of compounds of formula I, herbicidal composition containing as active ingredient a compound of formula I, and processes for severely damaging or killing unwanted plants by applying to the plants or to the growth medium of the plants an effective amount of a compound of formula I.

A process of removing unsaturation from resins by reaction with diimine. Thermally regenerable ion exchange resins are prepared by the hydrogenation of unsaturated polymers containing unquaternized amino groups with diimine. Procedures for generating the reactive diimine intermediate from precursors such as hydrazine are described.

Process for removing unsaturation from ion exchange resins containing

A process for making dimensionally-stable composite materials comprising adsorbents and magnetic particles embedded in a porous matrix of organic polymeric materials. The magnetic particles enable the composites to be easily and rapidly removed from treated solutions after the adsorption stage is complete.
