Polycarbonates of substituted cyclohexylindenebisphenols
First Claim
1. A thermoplastic molding composition comprising(A) an aromatic polycarbonate resin having a weight average molecular weight Mw of at least 10,000 containing bifunctional carbonate structural units corresponding to ##STR14## wherein R1, R2, R3, R4 independently represent hydrogen, C1l -C12 hydrocarbon radical or halogen;
- andR5, R6, R7, R8 and R9 independently represent hydrogen or C1 -C12 hydrocarbon radical, one of R5 and R9 representing hydrogen and the other C1 -C12 hydrocarbon;
in amounts of from 100 to 1 % based on the total amount of difunctional carbonate structural units in the polycarbonate.

Abstract
Aromatic polycarbonates having weight average molecular weight Mw of at least 10,000 which contain bifunctional carbonate structural units corresponding to general formula (I): ##STR1## wherein R1, R2, R3, R4 independently represent hydrogen, C1 -C12 hdyrocarbon or halogen radicals; and
R5, R6, R7, R8 and R9 independently represent hydrogen or C1 -C12 hydrocarbon radicals, one or R5 and R9 representing hydrogen and the other C1 -C12 hydrocarbon radical;
in amounts of from 100 to 1 mole % based on the total amount of difunctional carbonate structural units in the polycarbonate were found to be useful for thermoplast processing of compositions which are characterized by their improved toughness and high heat deflection temperature.
