Abstract

New light-polarizing articles (preferably in film form) are based on a polymer matrix which polarizers based on a polymer matrix which is constructed from polar or nonpolar monomer units or mixtures thereof, characterized in that polyacetylene is included as light-polarizing substance, said polyacetylene being obtained by polymerizing acetylene in solutions of said polymer matrix and thereafter processing the resultant polyacetylene/polymer solutions into polarizers.
