Influence of Compatibilizer on Blends Degradation During Processing
The thermomechanical degradation of blends made from polypropylene and polystyrene, with or without compatibilizer, was studied using an internal mixer coupled to a torque rheometer. The blends processed without compatibilizer presented regular and expected results regarding torque reduction, with evidence of chain scission. The blends processed with the block copolymer of styrene and butadiene...
متن کاملEffects of compatibilizer on immiscible polymer blends near phase inversion
e consider the effects of adding a PIB-PDMS diblock copolymer as a compatibilizer in model lends composed of polyisobutylene PIB and polydimethylsiloxane PDMS . The ratio of PIB to DMS was varied from 20:80 to 80:20 and, hence, these blends are dubbed “concentrated” blends. ost experiments were conducted on blends containing 0.01 or 0.1 wt. % compatibilizer. All lends had a droplet-matrix morph...
متن کاملStrain recovery of model immiscible blends without compatibilizer
The rheological properties of blends of immiscible homopolymers have received much attention in recent years (Tucker and Moldenaers 2002). Several publications have been devoted to examining the relationship between the rheology and morphology of two-phase blends. A key strategy employed by many researchers was to conduct experiments on ‘‘model’’ blends that were comprised of rheologically-simp...

در طی سالهای اخیراستفاده ازمنابع انرژی تجدید پذیر در شبکه های مدرن بنا به دلایل زیست محیطی و اقتصادی به طور گسترده استفاده شده است همچون نیروگاههای بادی و خورشیدی .ولتاژتولیدی این نیروگاهها اغلب به فرم dc می باشد وادوات الکترونیک قدرت به عنوان مبدل و پل بین شکل موج dc وac استفاده می شوند.این پروسه باعث ایجاد پالسهایی برروی شکل موج خروجی می شود که می تواند وارد تجهیزات قدرت همچون ترانسفورماتور ی...
15 صفحه اولEffect of compatibilizer concentration and weight fraction on model immiscible blends with interfacial crosslinking
eactive compatibilization, in which a compatibilizer is formed by an interfacial coupling between wo reactive polymers, is commonly used when blending immiscible homopolymers. We consider eactive compatibilization using two multifunctional reactive polymers, which leads to a rosslinked copolymer at the interface. Experiments were conducted on model blends of olydimethylsiloxane PDMS and polyiso...
