A termiticide comprising, as an active ingredient, a polymer which comprises repeating units of the formula:
-CxF2xO-
wherein x is an integer of 1 to 4, or the formula:
-CX₁X₂CF₂CF₂O-
wherein X₁ and X₂ are the same or different and each a hydrogen atom, a fluorine atom or a chlorine atom, provided that X₁ and X₂ are not fluorine atoms simultaneously, and has at least one polar group at polymer chain ends, which has no or little toxicity on the human beings or animals and long-lasting termiticidal effects.
一种杀白蚁剂,其有效成分包括一种聚合物,该聚合物由式中的重复单元组成:
-CxF2xO-
式中 x 为 1 至 4 的整数,或式中
-CX₁X₂CF₂CF₂O-
其中,X₁ 和 X₂ 相同或不同,各为一个氢原子、一个
氟原子或一个
氯原子,但 X₁ 和 X₂ 不能同时为
氟原子,且在聚合物链末端至少有一个极性基团,对人或动物无毒或毒性小,杀蚁效果持久。
