Abstract
In the previous papers of this series, it was reported that the cyclic monomer obtainedby vacum-distillation of the cyclic ethyl ester separated from thermally polymerizedethyl linolenate shows acute toxicity, and that this cyclic monomer seems to be the mainsubstance responsible for the toxicity of the polymerized ester.
It was also assumed that this cyclic monomer contains, as its main component, a compoundwith a cyclohexene ring in its molecule.
Experiment was conducted on the toxicity of a synthesized compound which has acyclohexene ring, and which has almost the same molecular weight as the cyclic monomerseparated from thermally polymerized ethyl linolenate.
Toxicity of this and also other cyclic compounds to rats was studied.
