Termination of vinyl halide polymerization |
摘要 |
An improvement in the method of terminating the preparation of vinyl halide-containing polymers is disclosed. The improvement comprises injecting into the polymerization reactor at the desired level of conversion a free radical inhibitor obtained by the alkylation of p-methoxyphenol with nonene. The free radical inhibitor also functions as an antioxidant in the polymer product.
