Patents Assigned to Buckman Laboratories International Inc
Abstract: Storage-stable glyoxalated polyacrylamide polymers and high solids aqueous compositions formulated with them are described. These glyoxalated polyacrylamide compositions can be used as additives for papermaking, providing paper with good dry and temporary wet strength, and increasing papermaking de-watering rates.
Enhancement of papermaking drainage and retention properties of aqueous cellulosic suspensions used for production of paper or paper board with a retention/drainage additive system including high solids glyoxalated polyacrylamide polymers in combination with silicon-containing microparticles is described.

Synthesis and Characterization of Different Molecular
The polyacrylamide was isolated and re-precipitated by pouring its solution into acetone. It was then dried under vacuum at 60ºC for 24 h. Synthesis of medium, high and very high molecular weight polyacrylamide High purity of the monomer and initiators and the absence of oxygen are essential in the polymerization process.

Global Polyacrylamide Market 2025 by Manufacturers
Polyacrylamide (abbreviated as PAM) is a polymer (-CH2CHCONH2-) formed from acrylamide subunits. It can be synthesized as a simple linear-chain structure or cross-linked. In the cross-linked form, the possibility of the monomer being present is reduced ev
High molecular weight (106–3 × 107 Da) polyacrylamide (PAM) is commonly used as a flocculant in water and wastewater treatment, as a soil conditioner, and as a viscosity modifier and friction

2/Polynary Retention System. Polynary retention system is composed of cation polymer and uffrafine particle filter aid. Its mechanism of action is to: when using, add the cation polymer first, causing paper feed components flocculation, and then treated by fan pump, rotary-screen high-shearing, larger pieces of paper material will be broken into small pieces, then feed the paper stock before
- What is partially hydrolyzed polyacrylamide (PHPA)?
- 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. The PHPA mud system stabilizes shale formations and influences cuttings and wellbore stability.

- 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.
- Is PHPA a water soluble polymer?
- PHPA is a co-polymer of anionic character and high molecular weight. It is a water-soluble polymer, which is primarily used as a highly efficient fluid loss reducer, Viscosifier and protective colloid for shale’s and cutting in fresh water, calcium, sodium brines and KCL mud systems.
- Which drilling fluid is compatible with PHPA?
- It is compatible with most of the drilling fluid products, biopolymers, PAC, CMC. It maintains borehole stability by preventing shale swelling and erosion. PHPA maintains viscosity in solid free drilling fluid. As a Bentonite extender in low solids non-dispersed mud, it can be used along with small addition of Bentonite to suspend weight material.
