White Cationic Polyacrylamide Emulsion , High Molecular
Our Cationic polyacrylamide Emulsion EC-8040 grade (CPAM) is a water based polymer. Anionic Polyacrylamide has a big range of high molecular weight from 6-12 million, with an anionic charge density ranging from 10-60%. EC-8040 grade has high molecular weight, and medium to high charge degree.
This invention discloses a process for the polymerization of acrylamide and for the copolymerization of acrylamide with other monomers. It employs a ferrous/hydroperoxide redox initiator system that greatly enhances the molecular weight of the polymer formed. These high molecular weight acrylamide polymers offer outstanding advantages in enhanced oil recovery as injection water viscosifiers.
Synthesis of High Molecular Weight Cationic Polyacrylamide
Cationic polyacrylamide is a derivative of polyacrylamide, a cationic polymer flocculant which has an excellent effect on sewage treatment. Our existing cationic polyacrylamide are mostly prepared by the Mannich reaction ,which has the shortcomings of more unreacted material, low cationic degree, poor stability, short validity, etc. Therefore, a cationic polyacrylamide has been prepared by

SYNTHESIS AND CHARACTERIZATION OF POLYACRYLAMIDE
Low temperatures promote synthesis of high mol ecular weight PAM (Lin, 2001). Actually, elevating the reaction temperature causes decrease in molecular weight on account of increase in the rate of
cosmetics (Yan 1998). For the same applications, high molecular weight polyacrylamide (PAM) has been widely used because of its effectiveness and low price, but it is nonionic. If a polymer has charged groups on its chain, it will be more effective as a retention aid in papermaking and as a flocculant. Hence, many cationic polymers are prepared by
Synthesis and characterization of a novel cationic
Its high molecular weight is favorable for improving the aggregation of colloids, thus promoting the separation of aggregates with water, but because of the inter-molecular and intra-molecular hydrogen bonding, chitosan can only be dissolved in an acidic solution through the interaction between H + and –NH 2.
Cationic Polyacrylamide, short name is CPAM, also called Cationic Polyelectrolyte, is copolymer of acrylamide and quaternized cationic monomer with different range of molecular weight from 5-12 million, and a charge density ranging from 10-60%. Our C-8050 grade has high molecular weight, and very high charge degree.

- Author to whom correspondence should be addressed. Poly aluminum-ferric Chloride (PAFC) is a new type of high efficiency coagulant. In this study, high iron type gangue is used as a main raw material. It is calcined at 675 °C for 1 h and 3% CaF 2 is added to the calcined powder and reacted with 20% hydrochloric acid at 93 °C for 4 h.
- What is high-purity poly-aluminum chloride (PACL)?
- Poly-aluminum chloride (PACl) is one of the common coagulants for water and wastewater treatment. A new Chinese national standard of PACl has been implemented, where the concentration of insoluble substances, iron and heavy metals is to be controlled strictly, then researches on the preparation of high-purity PACl are needed.
