Abstract

A method of functionalizing a thermoplastically processible olefinic polymer, comprising the step of: PA0 reacting in a melt, an olefinic polymer with a functionalizing agent having the formula ##STR1## wherein X.sub.1 and X.sub.2 are, independently, a OH group, a C.sub.1-10 alkoxy group, the group NR.sub.1 R.sub.2, or X.sub.1 and X.sub.2, taken together, are oxygen or the group --NR.sub.1 --; wherein PA0 R.sub.1 and R.sub.2 are, independently, hydrogen, a C.sub.1-10 (cyclo)alkyl group, a C.sub.1-10 hydroxyalkyl group, an aryl group with up to 10 carbon atoms, a C.sub.1-10 acyl group, or R.sub.1 and R.sub.2, taken together, are a C.sub.2-9 unsubstituted or hydroxyl substituted alkylene group.
