摘要:
Rubber curing agents such as quinoids are compounded to achieve a uniform or homogeneous distribution thereof in a rubber composition. The quinoid curing agents are initially solubilized in an organic polar solvent and then mixed with the rubber or rubber masterbatch. The organic polar solvent is then removed. A uniform fine distribution of the curing agent results in improved physical properties. The process is an improvement in that it does not require the rubber masterbatch be dissolved in a nonpolar solvent. The present invention is particularly suitable as a sealant composition for tires.
摘要:
Antireflective compositions characterized by the presence of an SiO-containing polymer having pendant chromophore moieties are useful antireflective coating/hardmask compositions in lithographic processes. These compositions provide outstanding optical, mechanical and etch selectivity properties while being applicable using spin-on application techniques. The compositions are especially useful in lithographic processes used to configure underlying material layers on a substrate, especially metal or semiconductor layers.
