| titleOfInvention | Polymer blend composition for use in optical devices |
| abstract | An optical polymer composition comprises a copolymer represented by the general formula (1) and a copolymer represented by the general formula (2) mixed in an arbitrary ratio: [-(A) n -(B) k -] (1) [-(A) m -(B) l -] (2) wherein A and B are different and selected from the group consisting of the repeating units of polyarylenesulfide, polyhaloarylenesulfide, polysulfone, modified polysulfones, polyhalosulfone, modified polyhalosulfones, polysulfonate, modified polysulfonates, polyhalosulfonate, modified polyhalosulfonates, polycarbonate, polyhalocarbonate, polyacrylate, polyhaloacrylate, polyarylene ether, polyhaloarylene ether, polyester, polyhaloester, polyolefines, polyhaloolefin, polyvinylhalide, polyoxole, polyhalooxole, polydioxole, polyhalodioxole, polythiol, polyhalothiol, polydithiol, polyhalodithiol, polyoxolane, polyhalooxolane, polydioxolane, polyhalodioxolane, polythiolane, polyhalothiolane, polydithiolane, polyhalodithiolane, polyimide, modified polyimides, polyhaloimide, modified polyhaloimide, polyamide, polyhaloamide, modibed polyamides, modified haloamides, polystyrene, polyhalostyrene, polysiloxane, polyhalosiloxane, polysilane, polyhalosilane, polymaleimide, polybismaleimide, polyhalomaleimide, polyphosphazene, polyhalophosphazene, polyphosphonate and polyhalophosphonate; wherein hydrogens (Hs) of C-H, O-H, S-H or N-H bond in the halogenated compounds are partially or entirely substituted by at least one selected from the group consisting of fluoride (F) and chloride (Cl); and 0<n<1, 0<k<1, 0<m<1 and 0<0<1, wherein n, k, m and I represent mole fraction and satisfy the conditions of n+k=1 and m+l=1, wherein a refractive index of the optical composition is controlled by changing the mixing ratio of the copolymer of general formula (I) and the copolymer of general formula (2). The blends are particularly useful for making wave guides and the refractive index can be finely controlled by adjusting the mixing ratio. |
