Notes:
The Wescan Model 232-A VPO was modified with a 12 volt regulated power supply for supplying bridge current and with thermocouples to allow for direct digital readout of the syringe box and measuring chamber temperatures. The modified instrument was used to measure Mn of standard (NBS) polyethylenes. Agreement with NBS values was good (within 10%) for Mn 〈 3 × 104 and fair (within 20%) for Mn = 1 × 105. Results on Mn of commercial polypropylenes are also reported.
