“…Much effort has been expended to modify the mechanical properties of PA‐6 by its blending with different thermoplastics, such as polyolefins. The compatibilization of the PA‐6/HDPE blend is important because PA‐6 presents high stress and flexural resistance together with good chemical resistance to polar solvents, whereas HDPE presents a high impact resistance and low moisture absorbance 4. Compatibilization of the immiscible PA‐6/HDPE blend is important for applications in food packaging because of the good oxygen barrier properties of the polyamide together with the moisture barrier properties of the polyolefin 5…”

Blends of polyamide and high-density polyethylene show adequate properties for a large range of applications: they are used for the production of filaments, containers, and molding resins. The effect of the addition of 2 wt % of a compatibilizer, maleic anhydride grafted polyethylene, to the blend was studied and compared to the use of postconsumer polyethylene. The samples were extruded with single-and twin-screw extruders with 25, 50, or 75 wt % f polyethylene, and the test specimens, molded by injection, were characterized by stress-strain tests, thermal properties, and morphologies. Processing the blends with postconsumer polyethylene in both extruders improved the mechanical properties in comparison to the blends processed with highdensity polyethylene and the compatibilizer. The morphologies of these blends showed that there was a decrease in the domain size of the disperse phase with the use of the compatibilizer or postconsumer polyethylene. The results indicate that for this blend, postconsumer polyethylene substituted, with advantages, for the necessity of a compatibilizer and the use of the high-density polyethylene.

The aim of this study was the establishment of quantification methods for binary mixtures containing a novel polypropylene/polyamide 6-based bicomponent fibre, for which a new generic fibre name has been requested to the European Commission. Application of such methods is requested by EU legislation to enable market surveillance of the compulsorycomposition labelling of textile products. Evaluating the key parameters for quantification, results showed that the b coefficient for the novel fibre (mass loss due to normal pre-treatment) is equal to 0%. In agreement with the members of the European Network of National Experts on Textile Labelling, the value of 1.00% was established as its agreed allowance (moisture regain in standard atmosphere), on the basis of the experimental value of 0.54%. Among the dissolution methods described in Directive 96/73/EC, the new fibre was insoluble in ten, for which the d correction factors (mass loss of the insoluble component) were evaluated. Three of them were additionally validated through an EU collaborative trial according to ISO 5725:1994. The ten established d correction factors were in the range of 1.00–1.01, revealing complete insolubility or up to 1% solubility of the novel fibre in the dissolution reagents. Based on this study, laboratories now have at their disposal methods to quantify the new fibre in binary mixtures with polyester, elastomultiester, polyamide, chlorofibres, certain acrylic and modacrylic fibres, acetate, triacetate, polylactide, certain cellulose fibres and certain protein fibres.
