Claims15
A graft copolymer comprising:
- a hydrocarbon backbone having a phenylene ether oligomer comprising repeating units derived from a substituted or unsubstituted monohydric phenol grafted therefrom,
- wherein the graft copolymer comprises a linking group -L1-(R)n-L2- between the hydrocarbon backbone and the phenylene ether oligomer,
- wherein
- L1 is a substituted or unsubstituted C1-6 alkylene group, a substituted or unsubstituted phenylene group or —(C═O)—,
- R is a substituted or unsubstituted phenylene group or —(C═O)—,
- n is 0 or 1, and
- L2 is a single bond or a C1-6 alkylene group;
- provided that when L1 is a substituted or unsubstituted phenylene group, n is 0.
