    摘要： A catalyst active in the preparation of alternating olefin/carbon monoxide (CO) copolymers is constituted by:(a) at least one salt of a metal of Group IB of the Periodic System,(b) a mono or bidentate ligand base containing one or two nitrogen or phosphorus atoms capable of linking to the metal atom by means of dative bonds,(c) a mineral or organic oxidizer agent.Also disclosed are the preparation of the catalyst and the use of said catalyst in alternated copolymerization of ethylene (C2) and/or other olefins with carbon monoxide (CO).

    摘要： Polymers having a very good combination of chemical, mechanical and process properties, and particularly useable either alone or as mixtures, as high-tenacity thermoplastic polymer and as elastomers or elastomeric modifiers, contain, randomly distributed along their chain, repeating cycloketonic structural units having the following general formula (I): ##STR1## wherein: A represents a tetravalent aliphatic or cycloaliphatic, substituted or non-substituted moiety containing a total number of from 4 to 50, preferably from 4 to 20, carbon atoms.Such polymers can be prepared by means of a process which comprises reacting, in a liquid media, a polydiene containing adjacent structural units derived from the 1,4-cis polymerization of conjugated dienes, with carbon monoxide, in the presence of free radical generating compounds and, optionally, a compound capable of acting as a hydrogen donor.
