Polyacrylamide
Polyacrylamide (abbreviated as PAM) is a polymer with the formula (-CH2CHCONH2-). It has a linear-chain structure. PAM is highly water-absorbent, forming a soft gel when hydrated. In 2008, an estimated 750,000,000 kg were produced, mainly for
Polyacrylamide Emulsions Handbook 3 z Dewatered emulsions For dewatered emulsions, the situation is different. They are not concerned by raincycle. As the content of water is very low there is no formation of skins and lumps during freezing or

- What is partially hydrolyzed polyacrylamide (PHPA)?
- Partially hydrolyzed polyacrylamide (PHPA), consisting of neutral acrylamide and anionic acrylate groups, is suitable for use in water with <25,000 mg/L TDS 12, 15.
- What does partially hydrolyzed polyacrylamide mean?
- What Does Partially Hydrolyzed Polyacrylamide Mean?
- Partially hydrolyzed polyacrylamide (PHPA) is a widely used polymer in the oil and gas industry due to its lesser cost and good water solubility. PHPA is used as a functional additive in water-based drilling fluids.
- When did polyacrylamide (PHPA) become available?
- Partially hydrolysed polyacrylamide (PHPA) became accessible in the foundation industry in the early 1990s ( Lam and Jefferis, 2014 ). Besides, PHPA can be applied in oilfield nowadays, especially in Daqing oilfield, where it is most superior with polymer flooding technique in China ( Zhong et al., 2025 ).
- Which polymer is used to produce partially hydrolyzed polyacrylamide (HPAM)?
- PAM is used to produce partially hydrolyzed polyacrylamide (HPAM), which is linear, anionic, water-soluble, stable, polymeric, and high molecular weight chain of acrylamide (C 3 H 5 NO) monomers (Bao et al., 2010; Braun et al., 2025; Liu et al., 2016; Xiong et al., 2018).
