Abstract: A process for the preparation of thermoplastic fibers which comprises:(a) spinning a solution of an alternating copolymer of an olefinically unsaturated compound and carbon monoxide, having a number average molecular weight of at least 5000, to fibers through a spinning aperture, said solution having a polymer content in the range of from 0.1-50% m(b) submitting the thus obtained fibers to a solvent-removal treatment to remove substantially all the solvent, and(c) stretching the thus obtained substantially solvent-free fibers in an environment having a temperature between the glass-transition temperature of said polymer and (T+20).degree. C., when T is the crystalline melting point of the polymer.

Abstract: A closable thermoplastic container for holding or conveying liquid hydrocarbon fuels and organic solvents, characterized in that at least those parts of said container which will come in contact with the liquid hydrocarbon fuels and organic solvents, is based on copolymers of CO or SO.sub.2, which polymers have been prepared by polymerization of CO or SO.sub.2 with at least one olefinically unsaturated compound A, and which polymers are made up of units --CO--(A')-- respectively --SO.sub.2 --(A')-- and in such a manner that the adjacent --CO-- respectively --SO.sub.2 -- units are separated by a single unit A', wherein the, or each, A' represents a monomer unit originating a compound A.

Abstract: A structural adhesive consisting of:a linear alternating copolymer or interpolymer consisting of carbon monoxide and at least one ethylenically unsaturated hydrocarbon.

Abstract: A process for producing a fiber reinforced polymer sheet by paper-making technology starting from an aqueous dispersion of thermoplastic polymer particles and fibers having a minimum length of 2.0 mm, characterized in that the polymer is an alternating copolymer of ethylene and carbon monoxide with an average weight molecular weight of at least 6000 and the fibers are used in an amount of from 5 to 450 pbw per 100 pbw of polymer.

Abstract: A vapor-emitter capable of continuously and slowly emitting vapors, and repeatedly and rapidly expelling a boost of vapors, into the atmosphere surrounding the container, comprising a container having at least one slow release generator positioned therein, characterized in that the container is provided with at least one opening at two different locations, the slow release generator being part of or forming a substantially vapor-tight partition between the locations and being in contact with the atmosphere on both sides of the partition, and expelling means being provided for expelling vapor-containing air from the container.

Abstract: Slow-release air freshener compositions having favorable depletion characteristics comprise an odorant (perfume) intimately dispersed in a polymeric mixture comprising 10-50% by weight of a certain block copolymer, 2-10% by weight polystyrene and 30-50% by weight of ethylene vinyl acetate copolymer.
