Abstract

Microscopic studies showed that popcorn growth of chloroprene rubber is anisotropic. This growth was obsd. by two methods: the McBain balance to follow the reaction continuously as a seed suspended in a bucket incorporates monomer from the vapor, and seeds were grown from liq. feeds to yield a single sample for weighing. The former method allowed oxygen, sulfur dioxide and nitrogen dioxide to be introduced at certain flow rates to growing popcorn. Each of these gases were found to terminate popcorn growth. Isoprene was found to reduce popcorn growth when added as a second monomer in the liq. feeds. 4-Oxo-TEMPO in the liq. feeds at certain concns. was able to inhibit popcorn growth but not permanently.
