Graft Copolymers for Blend Compatibilization: Mathematical Modeling of the Grafting Process
(Wiley VCH Verlag, 2012-10)
The grafting of PE onto PS through a Friedel-Crafts reaction, which results in a mixture of PE-g-PS copolymer, unmodified PE, and modified PS, is investigated. The copolymer may be suitable for compatibilization of immiscible ...
Mathematical modeling of the graft reaction between polystyrene and polyethylene
(Elsevier, 2011-04)
Polystyrene (PS) and polyethylene (PE) are two major components of household plastic waste whose blends are immiscible. Recycling them together is an attractive option that requires a compatibilization process to improve ...
Polyethylene-polystyrene grafting reaction: Effects of polyethylene molecular weight
(Elsevier, 2002-07)
Blending of different thermoplastic polymers usually results in segregated and low value materials for almost any mixing condition. Nevertheless, a synergetic combination of properties can be obtained by an adequate ...
Thermoplastic blend demixing by a high-pressure, high-temperature process
(John Wiley & Sons Inc, 2005-09-14)
The analysis of a thermoplastic polymer blend requires a precise separation of the blend components, which is usually performed by selective solvent extraction. However, when the components are high-molecular-weight polymers, ...
Catalytic Degradation of Polystyrene: Modeling of Molecular Weight Distribution
(Wiley VCH Verlag, 2011-06)
Two of the most abundant polymers in household waste streams, PS and PE, may be recycled by compatibilization through a Friedel-Crafts alkylation. This reaction produces a graft copolymer PE-g-PS that improves the properties ...
