Though silane chemistry has been used to crosslink unfilled polyethylene for many years, such crosslinking has only been recently applied to wood plastic composites to improve properties such as creep resistance. However, the presence of wood significantly changes the silane chemistry and a greater understanding is necessary for optimal processing and performance. We investigated three differen...

A six lump-based kinetic model has been developed for the hydrocracking of high-density polyethylene (HDPE) blended with vacuum gas oil (VGO) over a PtPd/HY zeolite catalyst. The blend (20 wt% HDPE and 80 VGO) hydrocracked in semi-continuous stirred tank reactor under following conditions: 400–440 °C; H2 bar; catalyst to feed (C/F) weight ratio, 0.05–0.1 gcat gfeed−1; reaction time, 15–120 min;...

Naïve Cotesia vestalis wasps, parasitoids of diamondback moth (DBM) larvae, are attracted to a synthetic blend (Blend A) of host-induced plant volatiles composed of sabinene, n-heptanal, α-pinene, and ( Z)-3-hexenyl acetate, in a ratio of 1.8:1.3:2.0:3.0. We studied whether qualitative (adding ( R)-limonene: Blend B) or quantitative changes (changing ratios: Blend C) to Blend A affected the olf...

Innovative ways of avoiding heavy plastic deposits all over the world must be designed and implemented via recycling post-used materials by reusing them as new products with better mechanical properties. As a result continuous use different materials, influencing effects on environment economic issues had been problem confronting post-consumer such materials. High-Density Polyethylene (HDPE) po...

A diacid monomer was synthesized by the condensation of L-tryptophan amino acid and pyromellitic dianhydride (PMDA). The diacid was utilized for the synthesis of three types of poly(amide-imide)s (PAIs) using three different kinds of diamines. The synthesized monomer and PAIs were characterized using FT-IR, 1H-NMR and 13C-NMR spectroscopies and the PAIs were also used ...

polycaprolactone (pcl) and poly(butylene terephthalate) (pbt) blend was prepared by melt processing. the pcl/pbt blend showed similar morphology with that of pure pcl.the crystallization temperature of pcl was increased by the incorporation of pbt. it was also observed that the peak height in the dsc thermograms decreased and then disappeared by adding 40 % or more pbt which might be due to the...
