An acrylic-modified polyolefin type ionomer (Ion., Zn2+), was successfully applied to compatibilize poly(ethylene terephthalate) (PET)/polyamide-6 (PA-6) blends. Melt-mixed blends were prepared at various PET/PA-6 ratios and at constant main component ratio, with various amounts of Ion., Zn2+. The techniques applied to characterize compatibilization were tensile testing, dynamic mechanical analysis,...
The compatibility of melt-mixed blends of a partially neutralized poly(ethylene-co-methacrylic acid-co-isobutyl acrylate) Zn2+ ionomer with a polyester-type polyurethane (PU), reported in Part 1 of this work, allowed application of the ionomer as a compatibilizer for incompatible PU/high-density polyethylene (HDPE) blends. The techniques applied were dynamic mechanical analysis (d.m.a.), tensile testing,...
The compatibility behaviour of melt-mixed blends of poly(ethylene-co-vinyl alcohol) (EVOH)/ionomer was studied in the complete composition range using tensile, dynamic mechanical, thermal, spectroscopic and morphology characterization techniques. The binary blends were mechanically compatible especially when equilibrated to ambient humidity levels. The above techniques were also applied to characterize...
Melt mixed blends of binary poly(vinyl alcohol) (PVOH)/ionomer, Zn 2+ and PVOH/ionomer, Zn 2+ /polyolefin ternary blends were characterized, the former in the complete composition range, using mechanical, thermal, spectroscopic and morphology techniques. Ionomer, Zn 2+ was a partially neutralized poly(ethylene-co-methacrylic acid-co-isobutylacrylate) terpolymer...
The compatibility behaviour of melt-mixed blends of an amorphous copolyester (poly(ethylene-co-cyclohexane 1,4-dimethanol terephthalate), PETG) with poly(ethylene terephthalate) (PET), was investigated over the complete composition range. The techniques applied were dynamic mechanical analysis, tensile testing and differential scanning calorimetry. The effect of thermal history was also examined...
The compatibility of melt-mixed blends of poly(ethylene terephthalate) (PET) with two types of poly(ether esters) (PEE) was studied over the complete composition range. The PEE used had a low (PEE-s) or a high (PEE-h) content of hard butylene glycol terephthalate (4GT) sequences. The techniques applied were dynamic mechanical analysis (d.m.a.), d.s.c., tensile testing and optical microscopy. Both...
Tensile, dynamic mechanical, thermal properties and morphology features of poly(ethylene terephthalate) (PET) blends with the acrylonitrile-butadiene-styrene (ABS) terpolymer were examined at up to 25 wt% content of ABS. Both unmodified and maleic anhydride grafted ABS (ABS-g MA) were used. PET/ABS blends quenched from the melt and tested shortly after, show good mechanical properties--the result...
The efficiency of four different compatibilizers melt-mixed with a poly(ethylene terephthalate)/high density polyethylene (PET/HDPE) blend was investigated. The compatibilizers studied were an ethylene-glycidyl methacrylate copolymer (E-GMA), an ethylene ethylacrylate glycidyl methacrylate terpolymer (E-EA-GMA), a hydrogenated styrene-butadiene-styrene copolymer grafted with maleic anhydride (SEBS-g-MA)...
Blends of poly(ethylene terephthalate) (PET)/poly(ethylene-co-ethyl acrylate) were found to have good mechanical properties when melt-mixed at optimum conditions, i.e. at 290°C for 25 min. Characterization studies based on tensile testing, dynamic mechanical analysis, differential scanning calorimetry and Fourier transform infra-red spectroscopy of blend extracts and morphological evidence using...
