How is polyacrylamide (PAM) a polymer with high molecular weight?

Polyacrylamide (PAM) with high molecular weight was synthesized by microemulsion method. Polyacrylamide was used as monomer, and a self-made initiator was used for polymerization under the condition of coexistence with sodium carbonate. The optimal polymerization parameters of PAM are determined: pH value of solution was 12. 3.

What are the preparation methods of polyacrylamide?

[Preparation method] The preparation methods of polyacrylamide can be summarized into 6 categories: ①water solution polymerization; ②emulsion polymerization, including inverse emulsion polymerization and inverse microemulsion polymerization; ③suspension polymerization; ④precipitation polymerization; ⑤solid polymerization; ⑥ Disperse polymerization

How to control acrylamide polymerization?

To conclude, the controlled polymerizations of acrylamide have been successfully achieved via a one-pot and one-step aqueous Cu (0)-mediated RDRP approach. It has been demonstrated that strong deactivation control is the key for the control in AM RDRPs.

How to synthesize uniform spherical polyacrylamide (PAM) hydrogel beads?

Synthesis of uniform spherical polyacrylamide (PAM) hydrogel beads in microreactors by using inverse suspension polymerization Ratio of the volumetric flow rates of the carrier (organic) phase and the aqueous phase (-) 1. Introduction

What are the three types of polyacrylamide (PAM)?

Polyacrylamide (PAM) and its derivatives are multifunctional water-soluble polymers, which can be divided into three types: nonionic, cationic and anionic. Polyacrylamide (PAM) with high molecular weight was synthesized by microemulsion method.

What is the standard state of polyacrylamide?

Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). ?) Polyacrylamide (abbreviated as PAM or pAAM) is a polymer with the formula (-CH 2 CHCONH 2 -). It has a linear-chain structure. PAM is highly water-absorbent, forming a soft gel when hydrated.
