This technique has been used to produce a variety of structures, including simple multi-arm star macromolecules with arms of identical chain length and composition (refs. 10, 36 and 37) and star polymers with arm asymmetry in length and/or composition (refs.
These two samples were submitted as part of an ASTM study on definitive testing of natural robber (ref. 10).
Toyota has demonstrated that significant improvements in the mechanical properties of nylon can be achieved in this manner (ref. 4).
A density of 1.14 g/[cm.sup.3] for these rubbers was previously reported (ref. 8).
A previous work (ref. 20) compared the micro IRHD and micro durometer instruments, looking at the effects of sample thickness, lateral dimensions, bent samples, temperature, retesting a previously measured spot and the effect of the foot force on the type M durometer.
Afterwards, the molded parts were submitted to a standard tensile test (refs. 3, 20 and 21) in order to check the adhesion strength.
These compounds reduce surface polarity, and some can chemically bind filler to polymer (ref. 1).
Since chain transfer preferentially occurs with large molecules, a branched molecule becomes more branched (ref. 3), generating gigantic molecules, macro-gel.
Literature reports of efficiencies between 800 and 8,000 g polymer per g vanadium possibly understate the latest developments with vanadium systems; however, it is generally accepted that significantly higher polymer yields are achieved with titanium (ref. 8).
He had previously worked on block copolymers produced by difunctional initiation (ref. 9) and he soon made an S-B diblock polymer of about 14% styrene content.
The most general strain energy function (excluding finite compressibility) proposed by Rivlin (ref. 1) is:
This empirical relationship sometimes works quite well; however, it does not have a theoretical basis, therefore it may not always work (ref. 23).
