摘要:
The present invention relates to thermoplastic moulding compositions consisting of halogen-free polycarbonates, styrene/maleic anhydride copolymers, phosphorus compounds of the formula (I) ##STR1## and tetrafluoroethylene polymers and, where appropriate, other known additives.
摘要:
This invention relates to thermoplastic moulding compounds free from nitrile groups, containing a mixture of randomly structured copolymers containing methyl methacrylate, maleic acid anhydride and aromatic vinyl compounds, aromatic polycarbonate resins and an elastomer grafted with methyl methacrylate.
摘要:
This invention relates to thermoplastic moulding compounds which are free from nitrile groups, obtained from randomly structured aromatic vinyl copolymers containing N-phenyl- or methyl-maleimide, aromatic polycarbonate resins and an elastomer grafted with methyl methacrylate.
摘要:
Aromatic polyesters based on diphenols, terephthalic and isophthalic acid and particular chain terminators exhibit an improved color number, an improved flowability and increased dimensional heat stability with otherwise comparable mechanical characteristics.
摘要:
Thermoplastic, branched aromatic polyphosphonates with average molecular weights (number average M.sub.n) of from 11,000 to more than 200,000, obtainable by transesterifying (a) from 97 to 100 moles of at least one diaryl phosphonate, and (b) from 0 to 3 moles of at least one triaryl phosphate--the sum of the moled of (a) and (b) being 100--with (c) from 90 to 99 moles of at least one aromatic dihydroxy compound, and (d) from 0 to 3 moles of at least one aromatic trihydroxy or tetrahydroxy compound--with the proviso that at least one of the components (b) and (d) is present in a quantity of at least 0.001 mole and that, where (b) and (d) are used, the maximum limit on the moles is 3.0.
