New silanes for silica modification in reinforcement of SBR compounds

Fields of application of silica filler in the reinforcement of synthetic or natural eleastomers for tyre industry. Here we present results of a new alkoxysilane coupling agent, sb1, obtained by grafting 3-mercaptopropyltrimethoxysilane onto polyburadiene oligomers. The aim is to obtain a modified filler with enhanced compatibility with the elastomer matrix
