Thermoplastic blends containing polycarbonates based on substituted cyclohexylidenebisphenols
First Claim
1. Thermoplastic blends ofA) 1 to 99% by weight of at least one thermoplastic aromatic polycarbonate which contains difunctional carbonate structural units of the formula (I) ##STR12## in which R1, R2, R3 and R4 independently of one another are hydrogen, a C1 -C12 -hydrocarbon radical or halogen and R5, R6 and R7 independently of one another are H or a hydrocarbon radical, with the proviso that at least one of the radicals R5, R6 or R7 is a hydrocarbon radical, that, when only one of the radicals R5, R6 or R7 is present as a hydrocarbon radical the latter is a C3 -C12 -hydrocarbon radical, except for C3 -C12 -n-alkyl, and that, when two or three radicals R5, R6 and R7 are present as hydrocarbon radicals, the latter are any C1 -C12 -hydrocarbon radicals, in amounts of 100 to 1 mol %, based on the total amount of difunctional carbonate structural units in the polycarbonate,B) 0 to 99% by weight of at least one amorphous thermoplastic which differs from (A) and has a glass transition temperature of 40°
- to 300°
C.,C) 0 to 99% by weight of at least one partly crystalline thermoplastic having a melting point of 60°
to 400°
C.,D) 0 to 99% by weight of at least one rubber,E) 0 to 99% by weight of at least one graft polymer of at least one rubber with at least one grafted polymer of at least one monomer from the group consisting of the vinyl compounds, acrylic and methacrylic compounds and maleic acid derivatives,in which the sum of A), B), C), D) and E) is 100% by weight.

Abstract
Thermoplastic blends of
A) 1 to 99% by weight of at least one thermoplastic aromatic polycarbonate which contains difunctional carbonate structural units of the formula (I) ##STR1## in which R1, R2, R3 and R4 independently of one another are hydrogen, a C1 -C12 -hydrocarbon radical or halogen and R5, R6 and R7 independently of one another are H or a hydrocarbon radical, with the proviso that at least one of the radicals R5, R6 and R7 is a hydrocarbon radical, that when only one of the radicals R5, R6 or R7 is present as a hydrocarbon radical this is a C3 -C12 -hydrocarbon radical with the exception of C3 -C12 -n-alkyl, and that when two or three radicals R5, R6 and R7 are present as hydrocarbon radicals these are any C1 -C12 -hydrocarbon radicals,
in amounts of 100 to 1 mol %, relative to the total amount of difunctional carbonate structural units in the polycarbonate, 1 to 99% of another polymer.
