    摘要： This invention relates to novel flame retardants (FR) resulting from the reaction of (a) or (b) with (c) where (a) is a compound containing at least one amine group and with at least one sixteenth of the amine molecules having at least one methylol bond, (b) is a phenol with at least one sixteenth of the phenol molecules having at least one methylol bond, and (c) is a mineral acid, organic acid, and organo-phosphorous acid, or a mixture thereof and optionally adding a polyhydric compound and/or optionally adding formaldehyde to the acid. These compositions are for use in general flame retardant applications such as coatings, adhesives, and articles made of polymeric materials. The FR mechanism by which these compounds generally perform as an FR agent is intumescence but the field of this invention is not restricted to that mechanism. Some of the compounds have substantial intumescence and others have very little intumescence but still are flame retardants.

    摘要： The present invention relates to anti-electrostatic polycarbonate compositions which are provided with chlorine- and bromine-free flame resistance and are distinguished by good mechanical and thermal properties and problem-free processability in the injection moulding process, i.e. by a good melt flowability and a low tendency towards juicing. The present invention also relates to the use of the polycarbonate moulding compositions according to the invention for the production of shaped articles and mouldings of all types, and the shaped articles and mouldings themselves.
