摘要:
1. A copolymer material for an ophthalmic device obtained by polymerization of a mixture comprising a) 30-60% w / w. or more aryl acrylic hydrophobic monomer of the formula (I) in which: A represents H, B represents (CH), S (CH), O (CH) or [O (CH)], u is 1-4, v is 1 -4, C represents (CH), m is 1-6, n is 1-10, Y is absent or represents O, S or NR, provided that if Y represents O, S or NR, then B represents by itself (CH), R represents H, CH, CH, where n = 1-10, iso-OCH, CH, or CHCH, w is 0-6, provided that m + w≤8, and D represents H , C-C1-6alkyl, C-Salkoxy, CH, CHCH, Br, F, Cl or I. b) 0.1-3.9% w / w. a macromer of formula (II) in which R and R are independently —CH, —CHCH, —CHCHCH, —CHCHCH — CH — CHCH — CHCH, —CHCHCH, —CHCHCH, or —CHCHCHCHCH, R is H, CH, or CHCH, z is 2-11 , ah denotes the number of repeating units and determines the molecular weight of the macromer, and is such that the molecular weight of the macromer is from about 300 to about 3500; c) 10-40% w / w. 2-ethylhexyl acrylate or n-octyl acrylate, d) 5-30% w / w. hydrophilic monomer selected from the group consisting of: hydroxy (C-C1-6alkyl) methacrylates, glycerol methacrylate and N-vinyl pyrrolidone; e) a crosslinking monomer, and f) a reactive UV absorber; where in this copolymer material for an ophthalmic device, the equilibrium water content at 35 ° C less than 4% .2. The copolymer material for the device according to claim 1, wherein the aryl acrylic hydrophobic monomer is selected from the group consisting of benzyl acrylate, 2-phenylethyl acrylate, 2-phenoxyethyl acrylate, 4-phenylbutyl acrylate, 5-phenylpentyl acrylate, 2-benzyloxyethyl acrylate, 3-benzyl acrylate, 3-benzyl acrylate, 3-benzyl acrylate, 3-benzyl acrylate1. Сополимерный материал для офтальмологического устройства, полученный полимеризацией смеси, включающейа) 30-60% масс./масс. или более арилакрилового гидрофобного мономера формулы (I)в которой:А представляет собой Н,В представляет собой (СН), S(СН), O(СН)или [O(СН)],u равно
