Claims17
A curable resin composition comprising a polycarbonate resin and a styrenic monomer, the polycarbonate resin comprising:
- a terminal structure that is derived from a (meth)acrylic monohydric phenol compound and is represented by Formula (1):
- wherein A is a vinyl group or an isopropenyl group,
- R1 is a single bond and R2 is selected from the group consisting of a single bond and a substituted or unsubstituted alkylene group having 1 to 20 carbon atoms,
- R3 is each independently selected from the group consisting of a hydrogen atom, a substituted or unsubstituted alkyl group having 1 to 20 carbon atoms, a substituted or unsubstituted alkoxy group having 1 to 10 carbon atoms, a substituted or unsubstituted aryl group having 6 to 12 carbon atoms, and a substituted or unsubstituted heteroaryl group having 5 to 12 elements,
- Z is —OC(═O)—,
- a is an integer of 1 to 3,
- b is an integer of 2 to 4, and
- Y is an ether group or an ester group;
- and
- a constitutional unit represented by Formula (2):
- wherein R4 is each independently selected from the group consisting of a substituted or unsubstituted alkyl group having 1 to 20 carbon atoms, a substituted or unsubstituted aryl group having 6 to 12 carbon atoms, a substituted or unsubstituted alkoxy group having 1 to 5 carbon atoms, and a substituted or unsubstituted aralkyl group having 7 to 17 carbon atoms,
- c is each independently an integer of 0 to 4,
- X is selected from the group consisting of —C(R5)(R6)—, —S—, —(CH2)d—, —O—, —SO—, —CO—, —SO2—, and groups represented by Formulae (3) to (6):
- wherein R5 and R6 are each independently a hydrogen atom, a fluorine atom, a chlorine atom, a bromine atom, an iodine atom, a substituted or unsubstituted alkyl group having 1 to 20 carbon atoms, a substituted or unsubstituted alkoxy group having 1 to 5 carbon atoms, a substituted or unsubstituted aryl group having 6 to 12 carbon atoms, or a carbocyclic group having 5 to 20 carbon atoms or a heterocyclic group having 5 to 12 elements formed by binding of R5 and R6,
- R7 is each independently a hydrogen atom, a fluorine atom, a chlorine atom, a bromine atom, an iodine atom, a substituted or unsubstituted alkyl group having 1 to 9 carbon atoms, a substituted or unsubstituted alkoxy group having 1 to 5 carbon atoms, or a substituted or unsubstituted aryl group having 6 to 12 carbon atoms,
- R8 is each independently a substituted or unsubstituted alkylene group having 1 to 9 carbon atoms,
- d is an integer of 0 to 20, and
- e is an integer of 1 to 500, and
- provided that X is not —C(CH3)2-when both c are 0.
