SummaryWe have investigated the effect of temperature on the chemical (hydrolysis) and thermal (molecular weight) stability of purified polyacrylamide solution.From viscosity and light scattering data we show that no polymer degradation due to oxygen contamination results from heating polymer solutions although higher temperature is responsible for hydrolysis of amide groups.

Do polyacrylamide-type polymers have good thermal stability?

Polyacrylamide-type polymers with good thermal stability present good long-term stability at high temperature and high salinity conditions. Viscosity reduction of polyacrylamide-type polymers with good thermal stability was owing to polymer main chain degradation at harsh conditions.

How to predict long-term stability of polyacrylamide-type polymer under high temperature and salinity?

A facile model was developed by TGA method for long-term stability prediction of polyacrylamide-type polymer under high temperature and high salinity conditions. Polyacrylamide-type polymers with good thermal stability present good long-term stability at high temperature and high salinity conditions.

Can thermogravimetric analysis predict long-term stability of polyacrylamide-type polymers?

This study aims to apply thermogravimetric analysis technology to develop a facile way for long-term stability prediction of polyacrylamide-type polymers at high temperature and high salinity reservoir conditions, to maintain sufficient viscosity in chemical flooding.

What is thermal stability of water soluble polyacrylamide (PAM) and partially hydrolyzed polymers?

Thermal stability of water-soluble polyacrylamide (PAM) and partially hydrolyzed polyacrylamide (HPAM) polymers under various solution conditions have been studied utilizing Quantum Mechanics Density Functional Theory (DFT) computational modeling method.

How much is polyacrylamide anionic grade in Germany?

The latest quarter-ending price for Polyacrylamide Anionic Grade in Germany was USD 3425/MT FD Hamburg, underscoring the sustained upward momentum in pricing driven by consistent industrial demand and regulatory pressures. The quarter was devoid of major plant shutdowns or operational disruptions, ensuring a stable supply amid rising demand.

Does cationic polymer P evolve during thermal decomposition?

In the present work, the thermal decomposition behavior of cationic polymers P (DMC-AM), synthesized in laboratory, was investigated in nitrogen by TG and DSC. The evolved gas during thermal decomposition process was analyzed by FTIR and MS.
