<p>Optical fiber comprising at least one epoxidized polyolefin based polymer coating, characterized in that the said coating is formed from a crosslinkable composition comprising: (a) at least one epoxidized polydiene oligomer having a first and a second end, the said oligomer comprising at least one hydrocarbon chain that is substantially free of ethylenic double bonds, at least one epoxide group at the said first end and at least one reactive functional group at the said second end; (b) at least one hydrogenated polydiene oligomer comprising at least one reactive functional group capable of reacting with the said epoxide groups; (c) at least one photo-initiator. Preferably, the said coating is a primary coating, preferably coated in its turn with a secondary coating.</p> |
