摘要： Thermoplastic polymer solutions in organic solvents are converted to granules of relatively uniform sizes and a narrow distribution range by passing the polymer solution through a jet nozzle to form a high velocity stream, injecting super heated steam into the high velocity stream to form a suspension of fine polymer particulates in a gas stream, passing the particulates into a heated agglomeration tube having a series of adjoining circular turns of at least 180.degree. wherein the particulates are substantially completely agglomerated into granules and the granules are recovered from the gas stream.
