摘要：
Diesters of well determined molecular weight and relatively narrow molecular weight distribution have been obtained by esterification of poly(ethylene glycol) with 1-naphthylacetic acid or 2,4-dichlorophenoxyacetic acid. The obtained diesters form interpolymer complexes with poly(acrylic acid) and with poly(methacrylic acid). They do not form complexes with pectin of low degree of esterification. The diesters exhibit auxin activity. The increase in the molecular weight of the polyether chain results in turning the inhibition effect into growth stimulation of mono- and dicotyledons.
