Abstract:
1. An article made from a heteroelement siloxane polymer, wherein the article has a refractive index in a range of from about 1.7 to about 2.8, wherein the article contains 0-50 atom percent hydrogen, wherein the heteroelement siloxane polymer has an empirical formula: Si w M x O y C z where M is an element selected from Groups IVA excluding Si or IVB; w+x+y+z=1; 0.5*y<w+x<1.5*y; and 0.1*y<w+x<6z; wherein the heteroelement siloxane polymer comprises: wherein R 1 , R 2 , R 3 , R 4 , and R 10 are independently selected from C 1 to C 10 hydrocarbyl groups, C 1 to C 10 halogen-substituted hydrocarbyl groups, hydrogen, or alkenyl groups; Z is independently selected from M or Si; M is an element selected from Groups IVA excluding Si or IVB; m, n and q are positive integers; m+n+q is greater than 4; and q is the number of branched points.
