Conductive polymers with ionic conductance including a non-aqueous complex of a polyester having the formula ##STR1## wherein: R.sub.1 and R.sub.2 are a C.sub.1 -C.sub.6 alkylene radical; G is a bivalent group deriving from H --(--O--R.sub.3 --).sub.p --O--R.sub.3 --OH with p=0 or 1-10 and R.sub.3 a C.sub.1 -C.sub.6 alkylene radical; X is CH.sub.2, S or O, and n=5-100; with an ionic compound. The polyesters having formula (I) wherein: X=S; R.sub.1, R.sub.2 and R.sub.3 are each --CH.sub.2 --CH.sub.2 --; p=1-10 and n=5-100, are also new.

Conductive polymers with ionic conductance

In the present invention disclosed are high-molecular-weight, soluble, thermoplastic branched polycarbonates endowed with improved properties, and suitable to blow-moulding fabrication. Such polycarbonates are characterized by the presence, in their structure, of units deriving from the following double-ring aromatic compounds: ##STR1## wherein R.sub.1 indicates H, --COCL, --SO.sub.2 Cl; R.sub.2, R.sub.3 and R.sub.4, equal to or different from each other, indicate --COCl or SO.sub.2 Cl. The above-said compounds are directly used in the syntheses.

Polycarbonate branched with double-ring aromatic compound

In the present invention disclosed are high-molecular-weight, soluble, thermoplastic branched polycarbonates endowed with improved properties, and suitable to blow-moulding fabrication. Such polycarbonates are characterized by the presence, in their structure, of units deriving from the following single-ring aromatic compounds: ##STR1## wherein R.sub.1 indicates H, --COCl, --SO.sub.2 Cl; R.sub.2, and R.sub.3, equal to or different from each other, indicate --COCl or SO.sub.2 Cl. The above-said compounds are directly used in the syntheses.
