    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.

    摘要: A process for the production of optically isotropic extrusion films is disclosed. Accordingly in a first process step a thermoplsatic resin is extruded to form a film having a thickness below 600 .mu.m. The second process step entailsa) calendering said film between a ground elastic roller and a high gloss steel roller to produce a film having a high gloss surface and a matt surface, orb) calendering said film between a lacquered elastic roller and a high gloss steel roller to produce a film having high gloss on both surfaces, orc) calendering said film between a ground elastic roller and a high gloss steel roller to produce a film having a high gloss surface and a matt surface, and then coating said matt surface with a melt of said thermoplastic polymer and calendering the resulting coated film between a high gloss steel roller and a ground elastic roller, with the high gloss side of the coated film facing the roller of elastic material.

    摘要: Aromatic cyanic acid esters are obtained by an improved process. Optionally substituted mononuclear phenols or polynuclear phenols optionally interrupted through bridge members such as ##EQU1## and/or divalent hydrocarbon bridges are condensated in form of an aqueous phenolate solution with cyanogen halide dissolved in organic solvents in the presence of catalytic quantities of a tertiary amine in a highly disperse system (two phase boundary reaction).The cyanic acid esters obtained are highly pure and stable.
