heterogeneous catalyst for the preparation of olefin copolymers alternating / carbon monoxide

摘要

a catalyst active in the preparation of alternating copolymers of olefins with carbon monoxide (co) is composed of: a) pd (cnet) (nhet.), supported on a solid support comprising silica ossldrilata preferentially.(b) a binder containing one or two mono or bidentato atoms of nitrogen or phosphorus is able to bind to the atom to pd by dativi links.(c) nobf is described the preparation of the catalyst and its use in the alternating copolymerization products of ethylene (c) and / or of other olefins with carbon monoxide (co).
