For example, it is now possible to prepare high molecular weight polymers (molecular weight > 50,000), to control the stereo-structure (tacticity) of the C–C main chain, and to quantitatively ...

The morphology is controlled by evaporation rate, polymer molecular weight, and template functionalization. The Nano Center Team is working in all of these areas and would be happy to meet with your ...

The makeup of polymer chains determines how strong ... The plastic additive also helps control the molecular weight of the synthesized material and, in turn, its properties and performance.

These polymers, although presenting a similar molecular weight and molecular weight distribution, have different physical structures which influence their performance in the target application. Hizkia ...

Researchers at Westlake University have disclosed a two-dimensional (2D) mechanically interlocked polymer (MIP) that mimics ...

The polymers were identified and characterized ... slightly shifted to higher elution volume (representing smaller molecular weight), suggesting that the acylation is favored in smaller molecular ...

The effect of the molecular weight dispersity (MWD) on the interfacial width between an end-tethered polymer brush and a free polymer matrix has been experimentally investigated by neutron ...

A ‘monomer unit' means the reacted form of a monomer in a polymer The weight percentage of molecules containing three monomer units or above should exceed 50% The weight percentage of any molecule of ...

In a test with a model polymer, they broke it down significantly, reducing its molecular weight from 58,100 g/mol to about 400 g/mol. When they applied the method to used rubber, it broke down ...

He became an instructor at Harvard, where he started experimenting with chemical structures of polymers with high molecular weight. In 1928, the DuPont chemical company did something unusual for a ...
