A low dielectric constant polymer, comprising monomeric units derived from a compound having the general formula I (R 1 —R 2 ) n —Si—(X 1 ) 4-n , wherein each X 1 is independently selected from hydrogen and inorganic leaving groups, R 2 is an optional group and comprises an alkylene having 1 to 6 carbon atoms or an arylene, R 1 is a polycycloalkyl group and n is an integer 1 to 3. The polymer has excellent electrical and mechanical properties. |
