In fact, the flocculation mechanism of polymer flocculation is closely related with structure.
The factors of influence the polymer viscosity-average molecular weight and the structure of the polymer were discussed.
The determination of star-P(AM-DMDAAC) structure: The purified star-P(AM-DMDAAC) was dissolved in heavy water as solvent.
All of this deduces to the conclusion that the structure of star-P(AM-DMDAAC) is shown in Fig. 8.

After stepwise optimization of processing parameters, products with martensitic structure and a small amount of bainite were obtained.
The strength levels just below 2000 MPa and elongation values A3=18 % achieved by a simple process in complex-shaped parts made of steel with cost-efficient chemistry can be considered a promising outcome.

An electrochemical cell can be described as a system by a differential equation, the form of which is determined by its internal structure, which varies with electrolysis conditions.
Chroming on non-stationary modes allows the most effective influence on the structure and physical-mechanical properties of coatings.
At higher or lower sulfate concentrations in the chroming electrolyte, the deposition process is unstable, which indicates a significant change in the film structure with a change in the sulfate concentration.
Structure of chrome coating Mathematical modeling of the chroming process was performed from a low-concentration electrolyte, where current variables (X1) in the range 60-80 A / dm2 and temperature (X2) (60 ... 80 °С) were taken as variables.

Modification of natural rubber through copolymer grafting starch onto natural rubber leads to a change of natural rubber chemical structure, which affect to a change of thermal properties such as degradation behavior during heating up.
The starch part as polar part and the natural rubber as non polar part building up chemical structure of the hybrid natural rubber-starch products, correlate with an enhancement of hydrophilicity and degradation of the both parts.
