ABSTRACT:
A moldable and/or extrudable poly(enamine ketone-co-alkylene ether) block copolymer is disclosed which has the formula shown below: ##STR1## wherein R' is H or alkyl, alkoxyl, cycloalkyl, cycloalkoxyl and aryl and aryloxyl, A is a poly(enamine ketone) sequence and B is a polyalkylene ether sequence. The poly(enamine ketone-co-alkylene ether) block copolymer is preferably prepared under mild condition by reacting a bispropynone with an amine-terminated poly(alkylene ether); a bispropynone with an organic diamine and an amine-terminated poly(alkylene ether); or by reacting a preformed propynone-terminated poly(enamine ketone) with an amine-terminated poly(alkylene ether).
The compolymers have excellent mechanical properties, are moldable and extrudable and are useful for the manufacture of articles such as films, sheaths, fibers for textile products, and other moldable and/or extrudable articles and RIM shaping. These materials are also useful as bonded or welded linings and as hot-melt adhesives.
