| titleOfInvention | Allylic polymer compositions with low yellow index, polymerizable compositions and lenses implementing them. |
| abstract | Polymer composition resulting from the polymerization of a polymerizable composition comprising: - at least 50% by weight of a monomer or of a mixture of monomers corresponding to formula (I): (CF DRAWING IN BOPI) in which; X denotes (CF DRAWING IN BOPI) and R and R ′ denotes H or CH3; . from 0 to 50% by weight of one or more vinyl allyl (s), acrylic (s) or methacrylic (s) mono or poly functional comonomer (s) (II) :. from 0.2 to 10% relative to the weight of components I + II, of a compound of formula (III): (CF DRAWING IN BOPI) in which R4 and R5 denote hydrogen or else one of the radicals R4 or R5 is a hydrogen atom while the other forms a ring with R2; R1, R2 and R3 are hydrogen, it being possible for alkyl to be substituted (s) by OH and / or interrupted (s) by an ether, ester or ketone function. |
