to describe the rheological behavior of polymer blends using emulsionbased (palierne theory) as well as micromechanical models (coranapproach), two immiscible polymeric blend systems of poly(trimethylene terephthalate) (ptt)/polyamide-12 (pa12) and ptt/polyethylene (pe) having different levels of molecular interactions were investigated as model systems. the role of interfacial interactions, vi...

Poly(p-phenylene terephtalamide) (PPTA), a high-performance polymer with high modulus and good hydrophilicity, is often used as a reinforced material. However, due to its high crystallity, micro-phase separation often occurs in the blends. In this paper, PPTA/poly(vinylidene fluoride) (PVDF) compatible blend solution was synthesized by in situ polycondensation. Blend ultra-filtration membrane w...

A weak protein solution extracted from chicken breast meat was exposed to three types of packaging materials. The crude myofibrillar protein solution (12.0 mg protein/mL buffer) was suspended in a 0.6M NaCl/NaPO4 buffer, then placed in bags made from either polyethylene (nonbinding film), a nylon blend (binding film), or Surlyn (binding film). Two separate experiments were conducted to determin...

ABSrRAcr: Material properties of composites prOOuced from ruycled plastics and ruycled ~ fiber were compared. A blend of high -density polyethylene aIKi polystyrene was used as a simulated mixed plastic. Stift'ness was generally improved by the addition of fiber, as expected, but brittleness also increased. Pre-treatment of the ~ fiUer with phenol-fonna1~ resins did not significantly a~t materi...

Field studies were conducted from 1992 to 1996 to select the most effective sex pheromone blend for mating disruption of the obliquebanded leafroller, Choristoneura rosaceana (Harris), in tree fruit orchards in Washington. Dispensers loaded with a 2-component pheromone blend, (Z)-1l-tetradecen-1-yl (Zll-14:0Ac) and (E)-1l-tetradecen-1-yl (Ell-14:0Ac), a 3-component blend that included the addit...
