• Beschreibung: Poly(vinyl formal) is a polymer that has been used extensively in the field of biochemistry. It has a weight-average molecular weight (Mw) of 66,000-75,000 and a hydroxyl group at one end. Poly(vinyl formal) is activated by hydrochloric acid, which is a strong acid catalyst. The process is carried out in an organic solvent to dissolve the polymer. The activation energy for this process is about 28 kcal/mol for the first step and about 50 kcal/mol for the second step. Poly(vinyl formal) crystallizes from solution with a combination of water and ethylene glycol as its solvent. This process occurs through a crystallization process that can be described by three steps: nucleation, crystal growth, and termination. Poly(vinyl formal) has functional groups such as carboxylic acid, alcohol, or amine groups on its backbone chain that are responsible for its water permeability. These functional
