Abstract
La presente invención se refiere a un macrómero polimerizable de radicales libres de la fórmula (I) basado en un perfluoroalquiléter no substituido osimétricamente substituido; un polímero que comprende el producto de la polimerización deun macrómero nuevo, sólo o junto con por lo menos uncomonómero vínilico; un procedimiento para la preparación de un macrómero y un polímero; piezas moldeadas, lentes de contacto, implantes córneos y artículosbiomédicos fabricados a partir de unpolíme ro; y artículos recubiertos con un macrómero de la fórmula (I) o un producto de polimerización del mismo.P1-(Y)m -(L-X1)p - Q-(X1-L)p -(Y)m -P1 (I) en donde cada P1 independientemente de los otros, es ungrupo p olimerizable deradicales libres; cada Y, independientemente de los otros, es -CONHCOO-, CONHCONH-, -OCONHCO-, -NHCO-, -CONH-, NHCONH-, -COO-, -OCO-, -NHCOO- ú-OCONH-; m y p, independientemente uno del otro, son 0 ó 1; cada L, indep endientemente de los otros, es un radical divalente de un compuestoorgánico que tiene hasta 20 átomos de carbono; cada X1 independientemente de los otros, es -NHCO-, -CONH-, -NHCONH-, -COO-, OCO-, -NHCOO- ú OCONH- ; y Q esun fragmento depolímero bivalente compuesto por los segmentos: (a) -(E)k-Z-CF2- (OCF2)x -(OCF2CF2)y -OCF2-Z- (E)k-, en donde x + y es unnúmero en el rango de 10 a 30; cada Z, independientemente de los otros, es un radical divalente que tienehasta 12 átomo s de carbono o un enlace; cada E,independientemente de los otros, es -(OCH2CH2)q-, en donde q tiene un valor de desde 0 a 2 y en donde la ligadura -Z-E- representa la secuencia -Z-(OCH2CH2)q-y k es 0 ó 1; fórmula (b) en donde n es unentero de 5 a 1 00; Alk es alquileno que tiene hasta 20 átomos de carbono; 80-100% de los radicales R1, R2, R3 y R4The present invention relates to a free radical polymerizable macromer of formula (I) based on an osymmetrically substituted unsubstituted perfluoroalkyl ether; a polymer comprising the product of the polymerization of a new macromer, alone or together with at least one vinyl comonomer; a procedure for the preparation of a macromer and a polymer; castings, contact lenses, corneal implants, and biomedical articles made from a polymer; and articles coated with a macromer of formula (I) or a polymerization product thereof. P1- (Y) m - (L-X1) p - Q- (X1-L) p - (Y) m -P1 ( I) where each P1 independently of the others is a polymerizable group of free radicals; each Y, independently of the others, is -CONHCOO-, CONHCONH-, -OCONHCO-, -NHCO-, -CONH-, NHCONH-, -COO-, -OCO-, -NHCOO- ú-OCONH-; m and p, independently of each other, are 0 or 1; each L, independently of the others, is a divalent radical of an organic compound having up to 20 carbon atoms; each X1 independently of the others, is -NHCO-, -CONH-, -NHCONH-, -COO-, OCO-, -NHCOO- or OCONH-; and Q is a bivalent polymer fragment composed of the segments: (a) - (E) kZ-CF2- (OCF2) x - (OCF2CF2) and -OCF2-Z- (E) k-, where x + y is a number in the range of 10 to 30; each Z, independently of the others, is a divalent radical having up to 12 carbon atoms or a bond; each E, independently of the others, is - (OCH2CH2) q-, where q has a value from 0 to 2 and where the ligature -ZE- represents the sequence -Z- (OCH2CH2) q and k is 0 or 1 ; formula (b) where n is an integer from 5 to 1 00; Alk is alkylene having up to 20 carbon atoms; 80-100% of radicals R1, R2, R3 and R4
