    摘要: This development is concerned with aromatic thermoplastic polycarbonates with special chain terminators which give the polymers enhanced hydrolysis resistance and impact toughness. These chain terminators are alkyl substituted monohydroxy phenyls in which each phenyl is substituted by one alkyl group having 8 or 9 carbon atoms and about 47 to 89% of its hydrogen atoms trisubstituted on carbon atoms with up to about 20% of the substituents in the ortho position and the balance at the para position. This development is also concerned with a process for synthesizing such polymers by using such chain terminators as reactants in generically known synthesis methods for polycarbonates.

The instant invention also relates to a process for the production of said thermoplastic molding compositions. These thermoplastic molding compositions show markedly improved resilience properties compared with known polycarbonates and can be employed as films and shaped articles in all cases where, on the one hand, high notched impact strength at low temperatures, high toughness properties at relatively high wall thicknesses, and transparency are required.
