Fibers having increased strength and small diameters can be produced from compositions comprising long chain branched syndiotactic vinyl aromatic polymers. Due to the increased fiber strength, less strand breakage occurs during processing which increases process productivity and yield.

Fibers made from long chain branched syndiotactic vinyl aromatic polymers

Long chain branched syndiotactic vinyl aromatic polymers can be obtained by polymerizing the vinyl aromatic monomer in the presence of a small amount of a multifunctional monomer under conditions such that a syndiotactic vinyl aromatic polymer is produced.

Long chain branched syndiotactic vinyl aromatic polymers

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.

A composition of matter comprising 25 to 99 parts by weight thermoplastic resin and 75 to 1 part by weight solid reinforcing agent having a surface coating of a polar group functionalized polyarylene ether.
