Influence of Copolymer Structure on Properties of Poly-β-Hydroxyalkanoatesthe base of the unit cell gets increasingly rectangular and the molecule develops a distinct herringbone or comb-like conformation. The organic synthesis of PHA copolyesters using alumoxane catalysts and racemic lactones yields crystalline products which mimic the properties of the natural polyester

Vernonia Oil: A New Reactive Monomereneous mixtures of commercial epoxy resin, diamine, and vernonia oil form thermosets consisting of a rigid epoxy matrix with randomly distributed small rubbery “vernonia” spherical particles which dissipate part of the impact energy. Finally, vernonia oil appears to be a low-cost substitute of epoxi

Einleitung und Problembeschreibung,ble to all starches. There are a number of ways for the determination of molecular weights and molecular weight distribution of poly(saccharides). Most of these are based on some form of calibration and can therefore only give values relative to a particular standard.
