Trunk lid of the Mercedes-Benz CL500 made out of polyamide blend allowing the integration of GPS and telephone antennae.

Afterfixing agent for improving the wet fastness properties of polyamide fibres dyed or printed with acid dyes. The light colour of this compound results in minimal effect on bright shades or white grounds of printed fabrics. Used to reserve polyamide when dyeing cotton/polyamide blends with direct dyes. 

REMOL ASN liquid has an excellent dispersing and compatibil-izing action in one-bath dyeing of wool or polyamide blends with acrylic fibers using anionic and cationic dyes and in dyeing polyester/acrylic fibers with disperse and cationic dyes. 

The introduction of the reactive oxazoline group into the triphosphazene ring has been achieved by the reaction of (NPC s and 2-(4-hydroxyphenyl)-2-oxazo-line, giving a hexasubstituted product (151).The reactivity of the oxazoline entities in (151) could be demonstrated by reaction with 4-benzoylbenzoic acid [formation of the photosensitive cyclophosphazene (152)] by the reactive blending with poly(ethylene terephthalate), and the compatibilizing activity for polycarbonate - polyamide blends. ... 

The addition of a copolymer has been shown to be a method of improving the mechanical properties of polyethylene/polyamide blends. One copolymer which has had particular success is poly(ethylene-co-methacrylic acid) (EMA) where the acid groups are partially neutralized by metal ions (EMA-salt). 

These parameters have been found useful to predict miscibility of blends containing one component whose structure systematically varied, e.g., polyesters with either halogenated polymers or Phenoxy [Prud homme, 1982 Harris et al, 1983 Woo ei al, 1985 Woo et al, 1986], polyamide blends [Ellis, 1989], ternary blends [Shah et al, 1986] and other systems, viz. SAN/ PMMA, SAN/PC, polyethyloxazoline/polyester, PPE with a mixture of P(oClS) and P(pClS), PC/PCL/Phenoxy, and many more. 

Ellis [1988-90] used the same approach to evaluate miscibility of polyamide blends. He treated their molecules as copolymers, viz. A B, ...

In comparing the different blends, the specific advantages of each type, as well as any potential overlap in performance with other type of blends have also been discussed. The fundamental advantage of polymer blends viz. their ability to combine cost-effectively the unique features of individual resins, is particularly illustrated in the discussion of crystalline/amorphous polymer blends, such as the polyamide and the polyester blends. Key to the success of many commercial blends, however, is in the selection of intrinsically complementing systems or in the development of effective compatibilization method. The use of reactive compatibilization techniques in commercial polymer blends has also been illustrated under the appropriate sections such as the polyamide blends. 

Commercial ABS/PA-6 blend exhibits excellent notched Izod impact (> 850 J/m) at room temperature and good drop weight impact (> 40 J) at -40°C. These impact properties are equivalent to the impact modified polyamide (Table 15.20). However, the DTUL (0.45 MPa) of ABS/PA blends are relatively low compared to those of impact modified nylons. The key difference being that in ABS/polyamide blends, due to the significant level of ABS, a substantial drop in the modulus occurs...
