Organolithium initiators maintain a partial covalent character to their bonding that allows for aggregation phenomena in hydrocarbon solutions (refs
. 7 and 8).
The RPA displayed superior statistical test sensitivity as measured from signal-to-noise (S/N) calculations (ref
This technology is currently used commercially in a premium tennis ball produced by Wilson Sporting Goods (ref
Development of specific formulations, reactive processing approaches and optimization of rheological and mechanical properties were previously reported (refs
. 7, 8 and 27).
The largest source of variation reported by Scott (ref
. 11) was the lack of agreement between laboratories.
Our own research (refs
. 11 and 12) concerning rubber-thermoplastics combinations suitable for two-component injection molding shows a good adhesion of PA 12 and PA 6.12 on different X-NBRs.
Similar to what previous workers found with polyamines (ref
. 20) and quaternary ammonium salts (refs
Also, observation of material during the incorporation step (refs
. 19 and 20) can hardly be described as a continuum.
A representation of the specific constrained geometry catalyst is shown in figure 1 (ref
In 1957 (ref
. 8), a process was described for the manufacture of polystyrene/polydiene block copolymers using alkyllithium initiators.
Strain invariants of the Green deformation tensor are defined by Rivlin (ref
. 2) as:
Correlation coefficients (r) for the statistical power law regressions for both the capillary rheometer and RPA data were calculated and reported in earlier work in 2000 (ref
