free-radical mechanisms such as polyvinyl chloride are usually atactic. Due to their random nature atactic polymers are usually amorphous. In hemi isotactic macromolecules...

Isotactic & atactic polypropylene is soluble in p-xylene at 140 °C. Isotactic precipitates when the solution is cooled to 25 °C and atactic portion remains...

(APAO; also known as atactic poly alpha olefin) is a commodity chemical used in multiple applications. In the mid-to-late-1950s, atactic polypropylene (APP)...

crystallization occurs much easier in isotactic than in the atactic polypropylene form. Atactic polymers crystallize when the side groups are very small...

GBR code) Appleton, Wisconsin, United States (by Amtrak station code) Atactic polypropylene, a hot-melt adhesive Authorized push payment fraud (APP fraud)...

three types of tacticity: isotactic (all substituents on the same side), atactic (random placement of substituents), and syndiotactic (alternating placement...

strong effect on the properties of the plastic. Standard polystyrene is atactic. The diastereomer where all of the phenyl groups are on the same side is...

alkyl substituents (R) is called atactic. Both isotactic and syndiotactic polypropylene are crystalline, whereas atactic polypropylene, which can also be...

adhesive had previously been asphalt but now is more commonly a hot-melt atactic polypropylene. Gummed tapes are described in ASTM D5749-01(2006) Standard...

ligands, it can produce polypropylenes with different tacticity. 1 creates atactic polypropylene, which is soft and amorphous with a free-flowing composition...

lactone lactide. In the presence of catalysts lactide polymerize to either atactic or syndiotactic polylactide (PLA), which are biodegradable polyesters....

rubber −70 −94 Polyvinylidene fluoride (PVDF) −35 −31 Polypropylene (PP atactic) −20 −4 Polyvinyl fluoride (PVF) −20 −4 Polypropylene (PP isotactic) 0...

Using metallocene 1 for polymerization of propene gives atactic polypropylene, while C2 symmetric metallocene 2 and Cs symmetric metallocene 3 catalytic...

decade[clarification needed] and currently accounts for 45% of world capacity. PVA is an atactic material that exhibits crystallinity. In terms of microstructure, it is...

mixed with filler components such as limestone, sand, or polymers such as atactic polypropylene (APP) that gives rigidity and tear resistance or styrene-butadiene...

stereogenic (colloquially: chiral). For this reason, polyacrylamide exists in atactic, syndiotactic, and isotactic forms, although this aspect is rarely discussed...

catalyst will determine the sequence of chirality in the chain, as in, atactic, syndiotactic, isotactic, as well as average block length, molecular weight...

that chloride is located on alternating carbon centres. PVC has mainly an atactic stereochemistry, which means that the relative stereochemistry of the chloride...

of PMMA can also be performed. The glass transition temperature (Tg) of atactic PMMA is 105 °C (221 °F). The Tg values of commercial grades of PMMA range...

can be used to direct whether the product is syndiotactic, isotactic, or atactic. Three views of ansa-dimethylsilylhafnocene dichloride (from X-ray coordinates)...
