THE EFFECTS OF REACTION VARIABLES ON SOLUTION POLYMERIZATION OF VINYL ACETATE AND MOLECULAR WEIGHT OF POLY(VINYL ALCOHOL) USING TAGUCHI EXPERIMENTAL DESIGN

Poly(vinyl acetate) is synthesized via solution polymerization, and then it is converted to poly(vinyl alcohol) by alkaline alcoholysis.The aim of the work study was to investigate statistically the influence of reaction variables in vinyl acetate polymerization, the conversion of this monomer to polymer, degree of branching of acetyl group in poly
