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.
