We studied the reaction of phenyl radicals (C(6)H(5)) with 1,3-butadiene (H(2)CCHCHCH(2)) exploiting a high temperature chemical reactor under combustion-like conditions (300 Torr, 873 K). The reaction products were probed in a supersonic beam by utilizing VUV radiation from the Advanced Light Source and by recording the experimental PIE curves at mass-to-charge ratios of m/z = 130 (C(10)H(10)(...

Tertiary amine-modified corn starches were converted to their basic or hydroxide form and combined with carboxylated butadiene-acrylonitrile copolymer and butadiene-styrene-sulfonic acid polymer to produce ionically bonded filler-elastomer composites. An increasing percentage of the elastomer fraction in the starch-elastomer composite is insolubilized as the starch-to-elastomer ratio increases....

Styrene-Butadiene-Styrene (SBS) is one of the most commonly used copolymer in PMB production. SBS modification results different material characteristics on neat bitumen depending type and course amount modification. Within scope this study, morphological characterisation modified samples involving (4%, 5% 6%) were examined by using innovative microscopies as AFM CLSM. The topographic phase pro...

Thermoplastic rubbers are materials that combine the characteristics of good processability of thermoplastics with the physical properties of vulcanized rubber. SEBS is a SBS which has been subjected to a hydrogenation process, through the polybutadiene chain is eliminated. This new rubber has a high resistance to environment, temperature, UV radiation, etc. without losing the properties of a t...

Polymer-modified bitumen is used to combat different pavement distresses and to increase the life span of pavement. Unmodified bitumen cannot perform better with the range extreme minimum and maximum pavement temperatures. The polymers commonly used to modify the bitumen are ethylene vinyl acetate (EVA) styrene butadiene styrene (SBS). The aim this study to compare the performance of EVA modifi...
