In the above formula, Q represents a divalent organic group having a substituted or unsubstituted aromatic ring; and A and A′ each independently represent an organic group. This polymer exhibits a sufficiently low dielectric constant for use as a semiconductor protection film and has the capability of forming a film at a relatively low temperature of 250° C. or lower.

Ten novelanalogues of flubendiamidecontaining a hexafluoroisopropanolmoiety were designed and synthesized. Their insecticidalactivities against armyworm (Pseudaletia separata Walker) were examined and compared with the commercial product flubendiamide. Compound 7b showed nearly the same insecticidalactivity as flubendiamide against armyworm.
