Abstract
A method of functionalizing a thermoplastically processible olefinic polymer, comprising the step of: 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 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.
Claims9
A method of functionalizing a thermoplastically processible olefinic polymer, comprising the step of:
- reacting in a melt at a temperature of about 180.degree.-320.degree. C., 99.9-96 wt. % of an olefinic polymer with 0.1-4 wt. % of a functionalizing agent having the formula ##STR5## 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
- R.sub.1 and R.sub.2 are, independently, hydrogen, a C.sub.1-10 (cyclo)alkyl group, a C.sub.1-10 hydrooyalkyl 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.
