Tenders are invited for providing and laying app (atactic
polypropylene polymer) modified prefabricated water proofing membrane on the profile sheet at horticulture office block at nsut campus
The content of atactic
fraction, determined by fractionation in n-heptane, was found to be, about, 1 % wt, which is characteristic of effective isospecific metallocene systems.
In 5% of cases, symptoms of the central nervous system e.g., ptosis, depression, dementia, atactic
gait, insomnia, personality changes and meningitis are reported .
Before the addition of the features, IHP incorrectly identified word phrases such as "36 schwannomas" (instead of "schwannomas") and "jerky movements" (instead of "atactic
The "Prima" series consist of plastomeric membranes modified with "Atactic
The most poignant example for how structural configuration of these materials affected the LCST is poly(N-isopropyl acrylamide) (PNIPAM): a gradual decrease is recorded with increasing the isotacticity, and, for an isotactic (mm) triad, the insolubility in water appears to be over 72%, although the atactic
(mr) PNIPAM is one of the representative water-soluble polymers .

Polymer Blends of Natural Poly(3-hydroxybutyrate-co-3-hydroxyvalerate) and a Synthetic Atactic
Classification of volatile products evolved from the temperature-programmed co-pyrolysis of Turkish oil shales with atactic
At earlier stage (1h) of the reaction, molar ratios of isotactic (mm), atactic
(mr), and syndiotactic (rr) pHEMA were 39, 13, and 48 mol%, respectively (Table 1).
The photoluminescence (PL) spectra for PPVA films exhibit broad emission bands which correspond to n [left arrow] [[pi].sup.*] electronic transition of the OH groups characteristic of three distinctive polymer configurations (isotactic, syndiotactic, and atactic
) in the aqueous solution.
