Recycling of Polyethylene Terephthalate Plastic Wastes based on unsaturated Diol
Cis -2-buten-1,4-diol, as an aliphatic unsaturated alcohol, was used to depolymerize polyethylene terephthalate beverage bottles waste in presence of zinc acetate as a transesterification catalyst. The diolysis processes were carried out near the boiling point of the diol, at atmospheric pressure and under nitrogen flow for predetermined periods, namely 5 and 10 hours.Weiterlesen...
Effect of Silica on the Performance of Natural Rubber/Poly (Vinyl Alcohol) and Starch Blend Films
The preparation of biodegradable polymer blend was made from natural rubber (NR) latex, starch solution and poly (vinyl alcohol) (PVA) solution by a latex-solution casting method. The swelling ratio of the polymer blend dramatically decreased as a function of silica content and NR content.Weiterlesen...
Biophysical Properties of Polymethyl Methacrylate Blended with some maleated vegetable Oils
Polymethyl methacrylate (PMMA) blended with maleated castor and soybean oils (COMA & SOMA) and with an aliphatic polyester based on polypropylene succinate (PPS) of varying blend compositions have been prepared to study their biophysical properties.Weiterlesen...
Effects of TESPT loading and mixing Condition on Properties of Silica-filled HNBR cured with Peroxide: Correlation of Bound Rubber Content, viscoelastic and mechanical Properties
Two different mixing conditions, i.e., normal condition (low mixing temperature/short mixing time) and extreme condition (high mixing temperature/ long mixing time), were employed for sample preparation. It was found that mixing at the extreme condition yielded significantly increased rubber-filler interaction.Weiterlesen...
