Kentucky Bluegrass Blend Ecology
… between varieties and seedlots within varieties. Blending seed using seed weight resulted in an actual composition similar to the intended composition. Including a susceptible variety in a blend resulted in more severe rust and powdery mildew than when not included. Likewise, including resistant …

The complex behavior of poly(dte) carbonate and its blend properties
… when PLLA, PLGA, and P(LcoDL)LA was blended with it. The desired outcome was to produce miscible polymer blends or significant phase shift in the blended materials which will make them at least partially miscible to each other. Differential scanning calorimetry (DSC) and thermally …

Formulation of Biodegradable Polysaccharide Blend as Replacement of Single-use Plastics
The accumulation of plastic waste has long been a problem and requires a multifaceted approach to address the complexity of this issue. Two heavy contributors are single-use plastics in the form of food packaging, and medical packaging. Conventionally, these are made of petroleum-based plastics as …

Morphology, Crystal Structure, Phase Transitions and Blend Compatibility of Thermotropic Liquid Crystal Terpolyesters
Compatibility of P7 and P7-X in binary blends with polyethylene (PE), polyethylene terephthalate (PET), and nylon 6 (Ny6), was examined to evaluate the effect of the aliphatic segment in promoting good adhesion at the interphase. Partial compatibility was observed for PE blends, while miscibility …

Structure Formation and Crystallization in Two-Phase Polymer Blend Flows (Fibers, Polyethylene, Polypropylene)
Flow induced crystallization of high density polyethylene and polypropylene has been studied in a two-phase flow system using linear low density polyethylene as the carrier phase. Extensional stresses were generated under slow flow conditions by either of two methods: one involving flow past a …
