    Abstract: A polymer mixture is prepared composed mainly of (1) an .alpha.-olefin copolymer containing a structural unit selected from the group represented by the general formula and ; wherein R represents a member selected from the group consisting of hydrogen and alkyl radicals having from one to four carbon atoms, and derivatives thereof, and (2) a poly-.alpha.-olefin. The polymer mixture is emulsified together with a compatible solvent and a dispersion medium. The emulsified dispersion is jet extruded through an orifice. The resulting paper-forming fibrous material has a morphological structure like that of wood pulp, and this has a significant effect on internal sizing of paper, because its anionic components have an improved affinity for typical paper-strengthening agents that are used in the preparation of paper products.

    Abstract: In preparing an emulsion from a poly-.alpha.-olefin, an organic solvent and a dispersion medium in order to produce a paper-forming material by the emulsion flash-spinning method, one of the following polymers is used as a surface active agent and hydrophilic polymer: (I) (II) (III) and (IV) a vinyl monomer-grafted polyvinyl alcohol, wherein A and B represent members selected from the group consisting of hydrogen, hydrocarbon radicals having from one to twenty carbon atoms, Li, Na, 1/2 Ca, 1/2 Mg, 1/2 Zn and 1/3 Al; R1 represents a member selected from the group consisting of hydrogen and a hydrocarbon radical having from one to thirty carbon atoms; R2 represents a member selected from the group consisting of hydrogen, -COOR3(in which R3 represents hydrogen or a hydrocarbon radical having from one to thirty carbon atoms), -OCOR? (in which R4 is a hydrocarbon radical having from one to twenty carbon atoms), halogen or -CH2OH; and R5 represents a member selected from the group consisting of -OCOR6 (in which R6 is a hydrocarbon radical having from one to twenty carbon atoms), -OH and -CH2OH.
