Abstract
Abstract PROCESSING AIDS OF IMPROVED DISPERSIBILITY IN LOW MOLECULAR WEIGHT POLY(VINYL CHLORIDE) COMPOSITIONS COMPRISE A SEQUENTIALLY PRODUCED POLYMER CHARACTERIZED BY 1 TO 30 WEIGHT PERCENT OF (A) A FIRST RELATIVELY SOFT STAGE CHARACTERIZED BY A GLASS TRANSITION TEMPERATURE OF 60*C. OR LESS; AND 99 TO 70 WEIGHT PERCENT OF (B) A FINAL SUBSTANTIALLY THERMOPLASTIC STAGE POLYMERIZED IN THE PRESENCE OF A PRODUCT CONTAINING THE FIRST STAGE, AND IN INITIAMATE CONTACT WITH THE FIRST STAGE AND FURTHER CHARACTERIZED IN THAT IF THE MONOMER OR MONOMERS WERE POLYMERIZED IN THE ABSENCE OF THE PRODUCT OF THE FIRST STAGE, A POLYMER WOULD BE FORMED HAVING A GLASS TRANSITION TEMPERATURE OF 25*C. OR GREATER.
