Provided are new functionalized nitrile rubbers, which may optionally also be in partially or wholly hydrogenated form, and also a process for preparing them by metathesis of nitrile rubbers in the presence of a metathesis catalyst and at least one functionalized allyl compound. The new functionalized nitrile rubbers are suitable for producing vulcanizable mixtures and allow the production of vulcanizates having very stable networks. Also made possible, in particular, is the synthesis of block copolymers.

A catalyst for silicone cross-linking is formed from treating a platinum tetramethyldivinyl disiloxane with a vinyl acetate for three or more hours to form a platinum tetramethyldivinyl disiloxane vinyl acetate. A low-temperature-curable liquid silicone rubber includes a polydimethylsiloxane; a crosslinking agent; the platinum tetramethyldivinyl disiloxane vinyl acetate catalyst; and a surface-treated silica filler.

A method for the methylation of amines, amides and imines comprises the step of reacting these compounds with CO.sub.2 and H.sub.2 in the presence of a Ruthenium-phosphine complex.
