ABSTRACT:
A (co)polycarbonate the molecular structure of which contains units derived from bisphenols conforming to formulae (1a1) and (1b1)in whichR1independently of one another represents hydrogen or a C1-C10-alkyl and R2represents C1-C10-alkyl, or phenyl or benzyl in each case unsubstituted or substituted by at least one member selected from the group consisting of hydrogen and C1-C10-alkyl radical.The (co)polycarbonate exhibits relatively high glass transition temperature and improved adhesion to metals.
