Notes:
Poly(vinyl chloride) (PVC) with relatively broader molecular weight distribution (BMD-PVC) was prepared by two-step suspension polymerization: (1) preparation of poly(vinyl chloride) with relatively higher molecular weight (HMW-PVC) and (2) successive preparation of poly(vinyl chloride) with relatively lower molecular weight (LMW-PVC) in the presence of the resultant HMW-PVC and 2-mercaptoethanol as a chain transfer agent. Some properties of BMD-PVC were investigated: fusion time, melt viscosity, discoloration time, tensile strength at yield, tensile modulus in tension, and elongation at break. © 1994 John Wiley & Sons, Inc.
