Claim 0:
1. A photocurable polymer composition for 3D printing comprising:
a UV-curable polyurethane oligomer represented by the following Formula 3;, a photoinitiator represented by the following Formula 5;, a silane coupling agent;
an oligomer; and
a stabilizer,
wherein,
n and m are the same or different and are each independently an integer ranging from 1 to 200,
A is a substituent represented by the following Formula 2, wherein * represents a moiety that is linked;, R2, R4 to R6 and R8 are the same or different and are each independently a substituted or unsubstituted alkylene group having 1 to 200 carbon atoms, a substituted or unsubstituted arylene group having 6 to 200 carbon atoms, a substituted or unsubstituted heteroarylene group having 5 to 200 nuclear atoms, or a substituted or unsubstituted cycloalkylene group having 3 to 200 carbon atoms; and
the substituted alkylene group, the substituted arylene group, the substituted heteroarylene group and the substituted cycloalkylene group are substituted with one or more substituents selected from the group consisting of hydrogen, deuterium, a cyano group, a nitro group, a halogen group, a hydroxyl group, an alkyl group having 1 to 30 carbon atoms, a cycloalkyl group having 1 to 20 carbon atoms, an alkenyl group having 2 to 30 carbon atoms, an alkynyl group having 2 to 24 carbon atoms, an aralkyl group having 7 to 30 carbon atoms, an aryl group having 6 to 30 carbon atoms, a heteroaryl group having 5 to 60 nuclear atoms, a heteroarylalkyl group having 6 to 30 carbon atoms, an alkoxy group having 1 to 30 carbon atoms, an alkylamino group having 1 to 30 carbon atoms, an arylamino group having 6 to 30 carbon atoms, an aralkylamino group having 6 to 30 carbon atoms, a heteroarylamino group having 2 to 24 carbon atoms, an alkylsilyl group having 1 to 30 carbon atoms, an arylsilyl group having 6 to 30 carbon atoms, and an aryloxy group having 6 to 30 carbon atoms, and when they are substituted with a plurality of sub stituents, these sub stituents are the same or different.
