Estimating the term…
Polymer compositions, typically thermoplastic polymer compositions, readily converted into electroconductive polymers and articles shaped therefrom, e.g., films, comprise at least one convertible polymer support substrate (A) and at least one amphiphilic heterocyclic monomer (B) having the formula (I): ##STR1## in which R.sub.1 and R.sub.2, which may be identical or different, are each a linear or branched alkyl, aryl, alkylaryl, arylalkyl, hydroxycarbonyl, alkoxycarbonyl or amide radical; X is an oxygen or sulfur atom or the divalent radical ##STR2## wherein R.sub.3 is a hydrogen atom or an alkyl, aryl, alkylaryl or arylalkyl radical; at least one of the substituents R.sub.1, R.sub.2 and R.sub.3 having an amphiphilicity-imparting number of carbon atoms.
A polymeric composition of matter which comprises at least one polymer support substrate (A) and at least one amphiphilic heterocyclic monomer (B) containing two conjugated sites of ethylenic unsaturation and at least one substituent having an amphiphilicity-imparting number of carbon atoms.
An electroconductive polymeric composition of matter which comprises at least one polymer support substrate (A) and at least one electroconductive polymerizate (C) having units derived from at least one amphiphilic heterocyclic monomer (B) containing two conjugated sites of ethylenic unsaturation and at least one substituent having an amphiphilicity-imparting number of carbon atoms.
The electroconductive polymeric composition of matter as defined by claim 29, wherein said at least one electroconductive polymerizate (C) is derived from a heterocyclic monomer having the formula (II)L ##STR10## in which R.sub.4 and R.sub.5, which may be identical or different, are each a hydrogen atom or a radical incapable of imparting amphiphilicity to said at least one polymerizate (C);
The electroconductive polymeric composition as defined by claim 21, said at least one polymer (A) comprising a thermoplastic polymer.
