Abstract:
Methods of processing high service temperature crosslinked thermoplastic gels are provided. The methods include combining (a) an oil-swelled physically crosslinked thermoplastic elastomer gel comprising at least one functional group configured to chemically crosslink in the presence of a crosslinker and (b) a crosslinker; maintaining the combination of the physically crosslinked thermoplastic elastomer gel and the crosslinker at a temperature at which they remain substantially unreacted; subsequently heating the combination to a temperature at which the oil-swelled physically crosslinked thermoplastic elastomer gel reacts with the crosslinker.

Abstract:
This invention relates flame retardant compositions containing low molecular weight brominated anionic, chain transfer, vinyl aromatic polymers, hereinafter “ACTVAP”. The compositions can accommodate high bromine content while still exhibiting a low thermally labile bromine content. The compositions have glass transition temperatures, Tg, that are predictive of acceptable melt flows and heat distortion temperatures (HDT) in HIPS and ABS based formulations substrates. The compositions, are suitable flame retardant candidates for use in thermoplastic formulations, e.g. polystyrene and ABS formulations.
