Claim:
A poly(ethynylene phenylene ethynylene polysiloxene(silylene)) polymer, said polymer corresponding to formula (I) below: or to formula (Ia) below: in which the phenylene group of the central repeating unit may be in the o, m or p form; R represents a halogen atom, a linear or branched alkyl group containing from 1 to 20 carbon atoms, a cycloalkyl group containing from 3 to 20 carbon atoms, an alkoxy group containing from 1 to 20 carbon atoms, an aryl group containing from 6 to 20 carbon atoms, an aryloxy group containing from 6 to 20 carbon atoms, a linear or branched alkenyl group containing from 2 to 20 carbon atoms, a cycloalkenyl group containing from 3 to 20 carbon atoms, an alkynyl group containing from 2 to 20 carbon atoms, an amino group, an amino group substituted with one or two substituents containing from 2 to 20 carbon atoms or a silanyl group containing from 1 to 10 silicon atoms, further, wherein one or more hydrogen atoms linked to the carbon atoms of R, may be replaced with one or more halogen atoms, alkyl groups, alkoxy groups, aryl groups, aryloxy groups, amino groups, amino groups substituted with one or two substituents or silanyl groups; n is an integer from 0 to 4 and q is an integer from 1 to 40; R′ represents: in which p is an integer from 1 to 40 and R 1 and R 2 , which may be identical or different, represent a hydrogen atom, a halogen atom, an alkyl group containing from 1 to 20 carbon atoms, a cycloalkyl group containing from 3 to 20 carbon atoms, an alkoxy group containing from 1 to 20 carbon atoms, an aryl group containing from 6 to 20 carbon atoms, an aryloxy group containing from 6 to 20 carbon atoms, an alkenyl group containing from 2 to 20 carbon atoms, a cycloalkenyl group containing from 3 to 20 carbon atoms, an alkynyl group containing from 2 to 20 carbon atoms, wherein one or more of the hydrogen atoms linked to the carbon atoms of R 1 and R 2 may be halogen atoms, alkyl groups, alkoxy groups, aryl groups, aryloxy groups, amino groups, disubstituted amino groups or silanyl groups; Y may represent a halogen atom, a halogen atom or a group derived from a chain-limiting agent.
