    摘要: Polyhalogenated benzyl esters having general formula (1), wherein X is halogen; n is an integer from 1 to 5; Y is an aliphatic chain, such as having at least 4 carbon atoms or a radical (2) wherein X has the same meaning as above, p is an integer from 0 to 5 and Z is (CH2)m where m is zero or an integer greater than zero. Y may be a saturated aliphatic chain, a linear or branched aliphatic chain having one or more unsaturations, or a substituted or unsubstituted aliphatic chain.
