Abstract
Olefin/carbon monoxide alternating polymers are flash-spun to form plexifilamentary products, pulp products, and foam products from alcohol or halogenated hydrocarbon solvents having 1 to 3 carbon atoms.
Claims2
A plexifilament consisting essentially of an alternating copolymer of ethylene and carbon monoxide or an alternating copolymer having alternating polymerized units of carbon monoxide and at least two different monomer units one of which is ethylene, and the remainder are selected from the group consisting of propylene, butene, pentene, hexene, heptene, octene, nonene, decene, dodecene, styrene, methyl acrylate, methyl methacrylate, vinyl acetate, undecenoic acid, undecenol, 6-chlorohexene, N-vinylpyrrolidone, and diesters of vinylphosphonic acid in which a majority of the monomer units are ethylene units.
