ABSTRACT:
Process is disclosed for preparing solid thermoplastic polymer fibrilla or fibril having a length which makes either useful for mixing with cellulosic pulp. Process involves forming a two phase mixture of polymer and solvent wherein one phase is a polymer-rich phase and the other is a solvent-rich phase. Said mixture is discharged through a suitable nozzle in laminar flow.
