Abstract
Provided is a polycarbonate resin having a structural unit (I) represented by formula (1) below: wherein L1 and L2 each independently represent a divalent linking group selected from an alkylene group, a cycloalkylene group, an arylene group, an oxyalkylene group, an oxyarylene group, and a group formed by combining two or more of these, where one or more hydrogen atoms of the linking group are optionally further replaced with substituents, and two of the substituents are optionally bonded to each other to form a ring structure.
Claims9
A polycarbonate resin comprising a structural unit (I) represented by formula (1) below:
- wherein L1 is a divalent linking group represented by any of formulas (i-1), (i-2) and (i-4) below, and
- L2 is a divalent linking group represented by any of formulas (ii-1), (ii-2) and (ii-4) below:
- wherein the symbol * represents a bonding position,
- R1 and R2 each independently represent an alkylene group having 1 to 20 carbon atoms, a cycloalkylene group having 3 to 20 ring-forming carbon atoms, an arylene group having 6 to 20 ring-forming carbon atoms, where one or more hydrogen atoms of these groups are optionally further replaced with substituents, and two of the substituents are optionally bonded to each other to form a ring structure, and
- 11, q11, p21, and q21 are each independently an integer of 1 to 10.
