Abstract
PURPOSE: To prepare a polymer of stabilized quality continuously by controlling the polymer melt viscosity within a limited range by such means as to determine the algebraic signs of the sum of the vacuum pressure difference values (in case of increase;plus, in case of decrease;minus), the average value of each polymer viscosity, and the gradient of the regression line obtained from said each viscosity versus time measured.
