The Tg depends on molecular parameters, such as, tacticity, molar mass, degree of crystallinity, polydispersion, branches or pending groups on the main chain [68], and experimental variables, such as, sample preparation, thermal history, rate of heating or cooling [69].
The polymer used in this study was a high tacticity isotactic polypropylene, iPP (F133A, Prime Polymer Co.
Among the many techniques for structural control of polymers, a particular attention is focused on the tacticity control in the radical synthesis of polymers.
The possible reason for the good behavior of the corrosion inhibition efficiency of poly(TBPMA-co-GMA) may be tacticity.
Kenise, a Sister of the order of St Joseph in South Australia, contacted me at my office at Monash University in 2009 to raise the possibility that Ruth employed a set of child rearing methods that were distinctly influenced by Aboriginal lifeways and Aboriginal women's practices of nurturing learning and self- sufficiency, grounded in play, tacticity and story.
Silane chemicals can be used during polymerization to modify catalyst activity and polymer tacticity.
based on the total weight of the polymer component of a propy-lene elastomer having a heat of fusion of less than 70 J/g and an isotactic triad tacticity of 50 to 99% and optionally containing units derived from a diene, the polymeric component having a density of less than 0.
Tacticity, in this case, corresponds to the relativity of that enlarging of the expressive boundaries, or rather in the fiction that seems to revolutionize a system that has been controlled for so long (but in the end affirms only the ideology of design as a liberation from any utilitarian servitude, and for this reason it is reduced, tactically, to a "representation").
Coverage includes types and properties of polymers, determination of elements, functional groups, determination of monomer ratios in copolymers, sequencing of monomer units in polymers, and stereoisomerism and tacticity regioisomerism.
Written by polymer researcher Roy Crompton, the book provides up-to-date information on the structure and microstructure of polymers, copolymers, and rubber; instrumentation needed to effect chemical and physical analysis of polymers; and detailed aspects of characterization including sequencing of monomer units in copolymers, end-group analysis, tacticity, and stereochemical determinations.
By precisely control of the tacticity distribution, the surface binding can be increased to improve non-woven fabric performance as well as sheet thermoforming.
