Question:
Use the regression models for molecular weight and viscosity to answer the following questions.
(a) Construct a response surface contour plot for molecular weight. In what direction would you adjust the process variables to increase molecular weight?
(b) Construct a response surface contour plot for viscosity. In what direction would you adjust the process variables to decrease viscosity?
(c) What operating conditions would you recommend if it was necessary to produce a product with molecular weight between 2400 and 2500, and the lowest possible viscosity?
Problem 6-26
An experiment was conducted on a chemical process that produces a polymer. The four factors studied were temperature (A), catalyst concentration (B), time (C), and pressure (D). Two responses, molecular weight and viscosity, were observed. The design matrix and response data are shown below:
