Effect on tensile properties

To circumvent any effect on tensile properties that might have concurred in the presence of the third monomer, hydroperoxide curing of E-P copolymer samples comparable in and... 

While we are dealing mostly with open-cell foams, control of the degree of openness also has an effect on tensile properties. Saunders reported on the control of open-cell structures by the addition of a stannous catalyst. They showed maxima...

The plasticizing effects of a larger number of metal stearates on the zinc sulfonate ionomer were examined, and the results are given in Table III in terms of flow and mechanical properties. Lead stearate, zinc stearate, and ammonium stearate significantly improved melt flow along with the stearic acid control. The barium, magnesium, sodium, lithium, and calcium stearates showed little, if any, improvement in melt flow. Of the four melt flow improvers, both stearic acid and ammonium stearate exerted deleterious effects on tensile properties. Only the zinc and lead stearates substantially improved tensile properties. Thus, while zinc stearate is not unique, the number of fatty acid derivatives that improve both melt flow and mechanical properties is limited. 

Samples 1, 5, and 6 in Table I illustrate a different series of chain-length increases. In this case the three ethyl substituents remain constant and the fourth substituent changes from methyl to octadecyl and then to behenyl. The relatively small effect on tensile properties of carbon atoms far out on the chain is again evident in comparing Samples 5 and 6. 

These references are concerned with the mechanisms through which moisture is absorbed by the fiber. The effect it has on fiber properties however varies from fiber type to fiber type, and although the effects are wider than merely the effect on tensile properties, it is on these properties that the standard methods of test are mainly concerned. Many of the standard tests previously cited, such as ISO 5079. ISO 2062. ASTM D 2256. and ASTM D 3217. all make provision for conducting the tests with the fiber or yarn in the wet rather than the conditioned state.

In automobiles, besides the large plastics parts, there is a substantial quantity of polymers that cannot be easily separated, viz. the interior trim made of PP, ABS, PC/ABS, PPE/PA, POM, etc. Recycling these commingled resins is more challenging, owing to lower value and high diversity of compositions. However, in some cases recycling can be simple — it was found that contamination of PP by as much as 15% of POM do not have detrimental effects on tensile properties, and it increases the modulus. The blends of PC/ABS as well as those of PPE/PA have also been profitably recycled.
