FIELD: chemistry.
SUBSTANCE: invention relates to stabilised polymer compositions containing a bromated polymer flame retardant particularly intended for producing foam material. The polymer composition contains a block polymer, e.g. a styrene copolymer, an aliphatic bromine-containing polymer and a mixture of at least one alkyl phosphite and at least one epoxy compound. The set of stabilisers which includes alkyl phosphites and epoxy compounds is very effective in preventing cross-linking reactions which occur when an aliphatic bromine-containing polymer is subjected to high temperatures which are found in melt processing processes.
EFFECT: invention improves processing and prevents gelling of the bromine-containing polymer during processing.
