Hydrolyzed polyvinyl alcohol pva

Manufactured by Merck Group
Sourced in United States

Hydrolyzed polyvinyl alcohol (PVA) is a synthetic polymer that is soluble in water. It is commonly used as a laboratory reagent and material in various applications. The core function of hydrolyzed PVA is to provide a water-soluble, biocompatible, and non-toxic material for research, development, and manufacturing processes.

The bleached bagasse pulp was supplied from Quena Company of Paper Industry, Egypt. The hydrolyzed polyvinyl alcohol (PVA) (average Mw 30,000–70,000) and sodium alginate (SA) (Mw = 1.93 × 105 g/mol) were obtained from Sigma-Aldrich, USA. Sodium metaperiodite (NaIO4), NaBr, and 2,2,6,6-tetramethylpiperidine-1-oxyl (TEMPO) were purchased from Sigma-Aldrich (St. Louis, MA, USA). Additional chemicals needed for the different analytical methods were bought from Sigma-Aldrich (St. Louis, MA, USA). All chemical reagents were used with no further purification.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
