    摘要： The present invention is related to high molecular weight polycarbonates based on aromatic dihydroxy compounds which contain 5 to 100 mol % preferably 20 to 100 mol % of structural units derived from .alpha.,.alpha.,.alpha.,.alpha.',.alpha.',.alpha.'-hexakisaryl-1,3-and/or -1,4-dimethyl benzene dihydroxy compounds. In a preferred embodiment, the polycarbonate is a copolymer of the hexakisaryl dihydroxy compounds and bisphenols known to be useful in producing polycarbonates. The residues of the hexakisaryl compound may be 5 to 90 mol %, preferably 20 to 70 mol % of the structural units. An especially preferred copolymer is that between the hexakisaryl compounds and .alpha.,.alpha.'-(hydroxyphenyl)-diisopropyl benzenes. These polycarbonates show improved heat stability and higher second order transition temperature points than conventional polycarbonates and are useful in applications involving high service temperatures such as electrical insulating film.

    摘要： A mixture comprising 1. from 70 to 99% by weight of a predominantly aromatic polycarbonate; and 2. from 30 to 1% by weight of a polyolefin graft polymer of (a) 70 to 95% by weight of a graft base consisting of a homopolymer of aliphatic and/or aromatic monoolefins or of a copolymer of these olefins, and up to 50% by weight of other monoolefinically unsaturated, radially polymerizable compounds and/or up to 5% by weight of diolefins, and (b) 5 to 30% by weight of at least one graft-polymerizable vinyl compound, the olefin graft polymers having been obtained by contacting a melt of the graft base (a) with oxygen or an oxygen-containing gas for at most 10 min. with intensive mixing under a pressure of from 1 to 150 bars and at a temperature of from 80.degree. C. to 300.degree. C., adding the vinyl compounds (b) to be grafted on immediately afterwards with intensive mixing in the absence of oxygen or oxygen-containing gas and removing the residual monomers after the graft polymerization reaction.
