Abstract
A compound of the formula: ##STR1## in which: (a) each of A and B independently is phenyl which may be unsubstituted or substituted; (b) each of R.sub.1 and R.sub.2 independently is hydrogen or C.sub.1 -C.sub.6 alkyl; (c) m represents an integer of from 0 to about 18; and (d) Z is poly(alkyleneoxy) which may be uncapped or capped with a C.sub.1 -C.sub.6 alkyl group. The compound can be grafted to polyolefin nonwoven webs by electron beam radiation without significant homopolymerization. The grafted webs are wettable (hydrophilic) and capable of withstanding multiple rewets without substantial removal of grafted compound. The grafted webs are especially well-suited for use in disposable absorbent products.
