Patent ID: 6950587

Claim:
Optical fibre comprising a core made of polycarbonate and a coating containing a polymer, which contains repeat units, derived from the monomers A) one or more different compounds of formula (I) in which m represents 2 D represents —(—CH 2 —) 4 —, R 1 is hydrogen or methyl, Z 1 represents a divalent radical of formula (II) in which A is an unsubstituted or substituted divalent radical of an aliphatic, cycloaliphatic, araliphatic or aromatic hydrocarbon, A 1 and A 2 , independently of one another, represent a member selected from the group consisting of —CH 2 —CH 2 —, —CH 2 —CH(CH 3 )— and —(—CH 2 —) 4 —, n represents an integer from 1 to 20, r represents an integer from 1 to 30, B) one or more different compounds of formula (III) in which R 2 is hydrogen or methyl, A 5 represents an unsubstituted or substituted divalent radical of an aliphatic or cycloaliphatic hydrocarbon, Z 5 and Z 6 , independently of one another, represent oxygen or N—H and R 3 is an unsubstituted or substituted alkyl, cycloalkyl or aralalkyl radical said coating containing 0.01 to 0.5% relative to its weight of a stabilizer selected from the group consisting of organic phosphate and organic sulphide.
