Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
62 words
An improved process for precipitating fibers from a polymeric solution, comprising: providing a solution of a non-crystalline polymer in a heated solvent; adding a linear isotactic crystalline polyalkene to said solution thereby forming a hot mixed polymer solution; and subjecting said mixed solution to mechanical or sonic vibration, while simultaneously lowering the temperature of said mixed solution to precipitate polymeric fibers thereform.
Claim 2
Dependent Claim
62 words

Claim 3
Dependent Claim
15 words
A process according to claim 1, wherein said non-crystalline polymer is a linear organic polymer.
Claim 4
Dependent Claim
14 words
A process according to claim 1, wherein said crystalline polyalkene is polypropylene or polyethylene.
Claim 5
Dependent Claim
18 words
A process according to claim 1, wherein said non-crystalline polymer is an acrylonitrile-butadiene-styrene terpolymer or a tetrafluoroethylene-hexafluoropropylene-vinylidene terpolymer.
