Abstract:
Fibers having increased strength and small diameters can be produced from compositions comprising long chain branched syndiotactic vinyl aromatic polymers derived from the polymerization of a vinyl aromatic monomer in the presence of from 10 to 1000 ppm, based on the amount of vinyl aromatic monomer, of a multifunctional monomer having more than one olefinic functionality. Due to the increased fiber strength, less strand breakage occurs during processing which increases process productivity and yield.
