説明
<jats:title>Abstract</jats:title><jats:p>Several 7‐membered lactam thioethers and lactam sulfones with methyl substituents have been synthesized and their polymerizability was compared with that of lactam, lactam ether, and lactam thioether. The polymerizability of substituted lactam thioethers showed parallel correlation with that of ε‐caprolactam and the substituent on the lactam ring decreased the polymerizability and lowered the melting, point of the polymer. However, organometallic compounds such as diethylzinc or alkylaluminum compounds had a marked catalytic effect on the polymerization, presumably owing to the reason that the ring‐opening reaction occurs at the thioether group.</jats:p>
