Injectable hydrogel formulations: Design, synthesis and appl …

Composite hydrogel of cross-linked polyacrylamide (PAAm) containing cellulose-g-poly(methacrylic acid) molecular brushes (MB) as a “soft” filler was prepared by thermoinitiated radical polymerization of acrylamide in the presence of MB. Interaction between linear …

Polyacrylamide Hydrogel Differences: Getting Rid of the …

Polyacrylamide hydrogels (PAAH) have been used for many years in European and Asian countries, and they have been and some still are produced by a number of different manufacturers (Table 1). None of the products are currently marketed in the U.S., but a …

Preparation of crosslinked lignin-polyacrylamide hydrogel wi …

In this work, we reported a process to produce high-temperature and high-salinity resistant polyacrylamide-based hydrogel by incorporating lignin into the polymer structure. The effect of lignin on the physical and rheological properties of the obtained polyacrylamide …

Gamma irradiation green synthesis of (polyacrylamide/chitosa …

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. In 2008, an estimated 750,000,000 kg were produced, mainly for water

… of Residual Acrylamide in Medical Polyacrylamide Hydrog …

Results Acrylamide was separated from polyacrylamide hydrogel. The concentration of acrylamide in polyacrylamide hydrogel ranged from 3.9×10-9 to 3.1×10-8g/L in the 20 clinical cases. The peak area was favorable linear and the range was up to 3 000 μg/L.
