Abstract
Polymers, methods of use thereof, and methods of decomposition thereof, are provided. One exemplary polymer, among others, includes, a photodefinable polymer having a sacrificial polymer and a photoinitiator.
Claims
exact text as granted — not AI-modified1 . A polymer composition, comprising:
a photodefinable polymer comprising a sacrificial polymer and a photoinitiator, the sacrificial polymer comprising an alkenyl-substituted polynorbornene.
2 . The polymer composition of claim 1 , wherein the photoinitiator is a negative tone photoinitiator.
3 . The polymer composition of claim 1 , wherein the photoinitiator is a positive tone photoinitiator.
4 . The polymer composition of claim 1 , wherein the photoinitiator is a free radical generators.
5 . The polymer composition of claim 1 , wherein the photoinitiator is selected from, bis(2,4,6-trimethylbenzoyl)-phenylphosphineoxide, 2-benzyl-2-dimethylamino-1-(4-morpholinophenyl)-butanone-1,2,2-dimethoxy-1,2-diphenylethan-1-one, 2-methyl-1[4-(methylthio)-phenyl]-2-morpholinopropan-1-one, 2-methyl-4′-(methylthio)-2-morpholino-propiophenone, benzoin ethyl ether, and 2,2′-dimethoxy-2-phenyl-acetophenone, and combinations thereof.
6 . The polymer composition of claim 1 , wherein the photoinitiator is selected from, bis(2,4,6-trimethylbenzoyl)-phenylphosphineoxide and 2-benzyl-2-dimethylamino-1-(4-morpholinophenyl)-butanone-1.
7 . The polymer composition of claim 1 , wherein the sacrificial polymer is about 1 to 30% by weight percent of the photodefinable polymer, wherein the photoinitiator is from about 0.5 to 5% by weight of the photodefinable polymer, wherein the polymer composition further comprises a solvent, wherein the solvent is about 65% to 99% by weight percent of the photodefinable polymer.Join the waitlist — get patent alerts
