Title (EN) MONOMERIC UNITS USEFUL FOR REDUCING THE MODULUS OF SILICONE HYDROGELS
(FR) UNITES MONOMERES UTILES POUR REDUIRE LE MODULE D'HYDROGELS DE SILICONE
Abstract: front page image
(EN)Monomeric units useful in reducing the modulus of hydrogels are disclosed. Silicone hydrogels including the subject monomeric units are especially useful in the formation of biomedical articles such as silicone hydrogel contact lenses. In formula (I), A is an activated unsaturated group; R and D independently are alkyl, alkylene or haloalkyl groups having 1 to 10 carbon atoms wherein said carbon atoms may include ether linkages therebetween; R¿1?, R¿2?, R¿3? and R¿4? are independently selected from: alkyl or haloalkyl groups wherein ether linkages may be included between carbon atoms; siloxane groups; and carbocyclic ring groups having from 6 to 18 carbon atoms; m is in integer from 1 to 500; n is an integer from 1 to 20; x and y are 0 or 1; z is 1 or 2; and x+y+z=3; so long as at least one of R¿1? or R¿2? is an alkyl group having from 1 to 10 carbon atoms.
(FR)Unités monomères utiles pour réduire le module d'hydrogels. Des hydrogels de silicone comportant les unités monomères de la présente invention sont particulièrement utiles dans la formation d'articles biomédicaux tels que des lentilles de contacts en hydrogel de silicone. Dans la formule (I), A est un groupe insaturé activé; R et D sont indépendamment des groupes alkyle, alkylène ou haloalkyle ayant de 1 à 10 atomes de carbone, lesdits atomes de carbones pouvant inclure des liaisons éther entre eux; R¿1?, R¿2?, R¿3? et R¿4? sont indépendamment choisis parmi des groupes alkyle ou haloalkyle, des liaisons éther pouvant être incluses entre des atomes de carbone, des groupes siloxane et des groupes de cycles carbocycliques ayant de 6 à 18 atomes de carbone; m est un nombre entier de 1 à 500; n est un nombre entier de 1 à 20; x et y valent 0 ou 1; z vaut 1 ou 2; et x + y + z = 3; à condition qu'au moins l'un parmi R¿1? et R¿2? soit un groupe alkyle ayant de 1 à 10 atomes de carbone.
