Abstract
Photo-crosslinkable materials comprising a linear polyamide and a 2-substituted anthraquinone as photo-crosslinking agent, the 2-substituted anthraquinone preferably being 2-acrylamidooanthraquinone, 2-acryloxyanthraquinone or 2-benzoylaminoanthraquinone.
Claims3
A photo-crosslinkable material comprising a linear polyamide selected from the group consisting of polyhexamethylene adipamide and polycaprolactam and a 2-substituted anthraquinone as a photo-crosslinking agent, said 2-substituted anthraquinone having the formula:
- ##STR3## where X is selected from a group consisting of NHC(O)CH.dbd.CH.sub.2, OC(O)CH.dbd.CH.sub.2, OC(O)C(CH.sub.3).dbd.CH.sub.2 and NHC(O)C.sub.6 H.sub.5.
A solvent-cast film comprising a polyamide having incorporated therein or coated on the surface thereof a 2-substituted anthraquinone having the formula ##STR4## where X is selected from a group consisting of NHC(O)CH.dbd.CH.sub.2, OC(O)CH.dbd.CH.sub.2, OC(O)C(CH.sub.3).dbd.CH.sub.2 and NHC(O)C.sub.6 H.sub.5.
A melt-spun fibre comprising a polyamide having incorporated therein or coated on the surface thereof, a 2-substituted anthraquinone having the formula ##STR5## where X is selected from a group consisting of NHC(O)CH.dbd.CH.sub.2, OC(O)CH.dbd.CH.sub.2, OC(O)C(CH.sub.3).dbd.CH.sub.2 and NHC(O)C.sub.6 H.sub.5.
