摘要 |
The present invention provides an optical polyacrylate polymer wherein at least 20% w/w of the total monomer repeating units are of the general formula (I): -(-CH2-C(R1) (COOR2)-)- wherein R1 is H or a C1 to C12 aliphatic and/or aromatic group, and R2 is an aliphatic and/or aromatic moiety containing at least one S atom. In further aspects, the present invention provides methods of making the above polymers, as well as planar lightwave circuits formed from such polymers. |
