摘要：

In this paper the unequivocal determination of the structure of the functional groups inserted into polyethylene moieties is described. Detection of the CH(COOEt)CH2COOEt groups, grafted on the polymer backbone by reaction of molten HDPE with diethyl maleate and with dicumyl peroxide as the radical-generating species, is accomplished by comparative analysis of13C NMR spectra of the functionalized polymer and two suitably synthesized model compounds: ethyl 3-carbethoxy-4-n-propylheptanoate and ethyl 3-carbethoxy-4-n-hexyldecanoate. © 1990, American Chemical Society.
