    摘要: What is disclosed is a method for sizing a textile yarn which comprises treating said yarn with a sizing solution comprising from 2.5 to 50 percent by weight of a polymer dissolved in an organic solvent, and then evaporating said solvent, said polymer being soluble in halohydrocarbons and being a saturated block copolymer comprised of at least two different unsaturated polymerizable hydrocarbons having two separated softening regions, one of which regions is below +20.degree. C. and one of which regions is above +20.degree. C., and wherein the blocks having the higher softening region form the disperse phase, i.e. above +20.degree. C., as well as sizing solutions for use in said method, and the sized yarns so produced.
