Abstract: A process is for preparing a self-healing composite material including a matrix of epoxy polymer in which a catalyst of ring opening metathesis reaction and vessels containing at least one monomer able to polymerize due to a ring opening metathesis reaction are dispersed. The process includes the preliminary step of dispersing at molecular level the catalyst in a mixture containing at least one precursor of the epoxy polymer, and then the steps of dispersing, in the mixture, the vessels and a tertiary amine acting as curing agent of the precursor, and the step of curing the mixture by at least a first heating stage performed at a temperature between 70 and 90° C. for a time between 1 and 5 hours, and a second heating stage performed at a temperature between 90 and 170° C. for a time between 2 and 3 hours.

Abstract: The process for preparing a self-healing composite material comprising a matrix of epoxy polymer, in which a catalyst of ring opening metathesis reaction and microcapsules containing a cyclic olefin having 7 to 40 carbon atoms are dispersed, comprises the steps of: preparing a mixture of a precursor of the epoxy polymer, having at least one oxirane ring, a curing agent chosen from the group consisting of tertiary amines, a Hoveyda-Grubbs II metathesis catalyst reaction, having the formula (I), wherein Ar=aryl having at least one halogen or alkyl substituent and “R=alkyl with 1 to 20 carbon atoms, and microcapsules containing a cyclic olefin having 7 to 40 carbon atoms; and heating the mixture at a temperature comprised between 25 and 130° C. for at least 1 hour, so as to obtain such matrix of epoxy polymer due to a reaction between precursor and curing agent, which reaction does not substantially involve either said catalyst or said microcapsules.

Abstract: The invention relates to copolymers of alkenes and conjugated dienes containing cyclopropane and cyclopentane rings in the main chain. These copolymers are charachterised in that the amount of cyclopropane units is between 0.1% and 50% by weight and that the molar percent of the cyclopropane units is higher than the molar percent of the unsubstituted cyclopentane units.
