Acyl Esters from Oxo-Derived Hydroxymethylstearates as Plasticizers for Polyvinyl Chloride
Hydroxymethylstearates were made by hydroformylation or oxo reaction of monoand polyunsaturated fats and esters with either rhodium-triphenylphosphine or cobalt carbonyl catalysts. Rhodium-oxo products were hydrogenated with nickel catalyst, whereas, cobalt-oxo products were heated directly under hydrogen pressure. Hydroxymethyl fatty alcohols also were prepared by a two-step copper-cmomite hyd...
متن کاملBiodegradable single-polymer composites from polyvinyl alcohol
The microstructure and thermomechanical behaviour of a novel fully biodegradable polyvinyl alcohol (PVOH)-based single-polymer composite (SPC) is presented. Three kinds of PVOH stapled fibres, having different melting temperatures and tensile mechanical properties, were considered as a reinforcement, whilst plasticized PVOH granules were selected as a continuous matrix. Calorimetric tests on th...

متن کاملPolyvinyl alcohol particle superficial morphology.
We appreciated the research by Derdeyn et al (1) from the Mallinckrodt Institute of Radiology concerning the size and suspension characteristics of polyvinyl alcohol (PVA) particles. We do agree that both size and suspension characteristics of PVA represent relevant parameters affecting the aggregation of particles during injection. In addition to these two variables, we considered further para...
