The influence of stereochemistry of polar modifiers on the microstructure of polybutadiene and poly(styrene-co-butadiene) was evaluated for 2,2′-ditetrahydrofurylpropane (DTHFP). The meso and d,l diastereomers were isolated from commercial 50/50 mi

1,4-polybutadiene (PB) of varying molecular weight, M , and varying polydispersity (obtained by mixing monodisperse PB) was characterized. As is well-known, some rheological properties are affected by both molecular-weight and polydispersity; however

The cyclic deformation of filler reinforced elastomer compounds results in energy losses caused by a partial hysteretic breakup and subsequent reformation of the filler network. This phenomenon has significant socio-economic consequences as it affect

The preparation and characterization of a class of alkoxy-modified silsesquioxane (AMS) compounds containing less than 5 wt % of latent alcohol is described. The AMS derived from octyl triethoxysilane (OTES) behaves as a shielding agent in silica-fil

Polybutadiene and poly(butadiene-co-styrene) elastomers were prepared in high conversions using 2-lithio-2- methyl-1,3-dithiane as the initiator. Polymers were readily prepared with a polydispersity index (PDI) of 1.05 to 1.26 and a Mn of up to 208 k

Understanding the dynamics of the glass transition of polymers and molecular liquids has been a goal of physicists for more than a half-century. The nature of this transition is directly linked to the heterogeneity of the dynamics, reflected in spati

Filler flocculation and polymer-filler interaction in silica and carbon black filled rubbers containing different functional end-groups were investigated. Lithium-hexamethyleneimine initiated polymers terminated with a proton (HMI-P-H), SnCl4 (HMI-P-

Hydrogen peroxide and a trace of either ethene or propene initiated the conversion of ethane to propionic acid and its mixed anhydride (CH3CH2CO2H + CH3CH2COOCOCF3) and trifluoromethyl ethyl ketone, CH3CH2COCF3, by trifluoroacetic anhydride at 80 °C

In water, metallic palladium on carbon was found to catalyze the deep oxidation of organophosphorus and organosulfur compounds by dioxygen at 90°C in the presence of carbon monoxide. This system presents the first examples of catalytic cleavage of p
