摘要: Abstract: Mesoporous silica is used as filler for styrene–butadiene rubber (SBR); filler–polymer interactions are compared with those exhibited when commercial ultrasil (VN3) used. A silane coupling agent added to improve the dispersion and its influence on bound formation also investigated before vulcanization. The content higher mesoporous increases further sample containing alquil silanes improving mechanical properties. For vulcanized samples, reinforcing measured by vulcanization degree swelling degree, elastic modulus glass transition temperature (Tg) samples increased use of organosilane (bis- trietoxisililpropil tetrasulfano (TESPT) or bis-trietoxisililpropil disulfano (TESPD) during kinetics SBR evaluated rheometry differential scanning calorimetry. rate filled indicating autocatalytic effect. This can be explained chemical between penetration chains into mesopore.
