Ethene, 1,1′-[methylenebis(oxy)]bis-, homopolymer

Description:

Ethene, 1,1′-[methylenebis(oxy)]bis-, homopolymer, commonly known as poly(ethylene glycol) or PEG, is a synthetic polymer characterized by its repeating ethylene glycol units. This polymer is typically colorless, odorless, and non-toxic, making it suitable for various applications in pharmaceuticals, cosmetics, and food industries. It exhibits excellent solubility in water and a range of organic solvents, which enhances its versatility. The polymer's molecular weight can vary significantly, influencing its physical properties such as viscosity and melting point. PEG is known for its hygroscopic nature, allowing it to retain moisture, which is beneficial in formulations requiring hydration. Additionally, it possesses biocompatibility, making it ideal for medical applications, including drug delivery systems and tissue engineering. Its low immunogenicity and ability to form hydrogels further contribute to its utility in biomedical fields. Overall, the characteristics of this polymer make it a valuable material in both industrial and research settings.

Poly(vinyl formal), Mw66,000-75,000

CAS: 9003-33-2

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
