Network formation of low molecular weight ‘liquid’ polymers studied by gel permeation chromatography and stress-strain analysis according to Mooney-Rivlin

The rheological and mechanical properties of elastomers are defined by their different networks: crosslink network the filler network. is influenced polymer structure. – particularly in case silica as depends on interaction between particles polymer. Liquid polymers can affect these networks lower molecular weight with certain types functional groups. goal present work to gain a better understanding formation: 1. During sulfur curing pure liquid polybutadienes concentrations curatives, 2. Through differently added polymer-silica-masterbatches cured silica/SSBR mixtures. For first point, pre-cured samples were analyzed gel permeation chromatography. results indicate an association concentration chain length. second stress-strain analysis according Mooney-Rivlin provides information about main when it throughout masterbatch approach.
