12.1 INTRODUCTION

Chemical dehydrohalogenation of some halogen-containing polymers [1] is
known to be one of the most convenient and accessible methods for syn-
thesizing carbynoid structures. The latter are generally defined as carbon-
rich chain-like poly(or oligo)mers with both polyyne- and cumulene-type
moieties, extended interchain cross-linking as well as end-capping and/or
pendant side groups [2].
