Abstract
A polymer which can be crosslinked by high-energy radiation and contains from 0.1 to 50% by weight, based on the polymer, of 2,3-dihydrofuran groups or derivatives thereof, each calculated as 2,3-dihydrofuran.
Claims12
A polymer, comprising:
- 0.05 to 50% by weight of at least one 2,3-dihydrofuran group per 100% by weight of said polymer;
- wherein said polymer is a side chain polymer;
- wherein said 2,3-dihydrofuran group is attached to said polymer via a functional group;
- wherein said polymer is cross-linked by reacting the double bond of said 2,3-dihydrofuran group when exposed to high-energy radiation.
