The Effect of 1,3 Bis (citracon-imidomethyl)benzene in Silica Containing Compounds

摘要

The effect of 1,3-bis (citraconimidomethyl)benzene (Perkalink 900) has been investigated in silica containing off-the-road (OTR) and "green tire" compounds. It has been demonstrated that by using Perkalink 900 it is possible to reduce the level of silane coupling agent, bis-(3-triethoxysilylpropyl)tetrasulfide (TESPT) both in OTR as well as in "green tire" compounds providing either equivalent or better performance characteristics such as improved reversion resistance, lower heat build up ad enhanced blow out times. The polymer-filler and filler-filler interaction parameters virtually remain unchanged indicating no detrimental effect on reinforcement characeristics. The network studies has been been done suggesting that Perkalink 900 provide better heat resistance because of the incorporation of thermally stable as well as flexible C-C crosslinks during the reversion regime.
