The IUPAC name is poly(1-carboxyethylene). They may be homopolymers of acrylic acid, or crosslinked with an allyl ether of pentaerythritol, allyl ether of sucrose, or allyl ether of propylene. In a water solution at neutral pH, PAA is an anionic polymer, i.e. many of the side chains ...
Very good info. Thanks. However, this carbomer homopolymer is kind of scary. It's also used in a number of OTC vaginal lubricants and moisturizers. I can't imagine using anything for delicate lady parts with the words "poly-alcohol or allyl ethers" in it. After 20 years of menopause, ...
Poly(ε-caprolactone) has a melting point of 59-64°C and a glass transition temperature of -60°C. It is a low molecular weight, colorless crystalline solid with a waxy texture. The introduction of ester groups -coo- in the molecular structure makes it easily biodegradable by microorganisms ...
