hi guys, i'm studying for an exam and i'm going nut searching for a book that describe what i'm looking for. can some of you tell me if a solution containing a polymer has a greater viscosity if the polymer is in an entangled form (polymer has some affinity for the solvent but still intramolecular bond are holding) or if the polymer chains are in a more straight conformation? pls link some book/article/paper if you can.

What units are used when calculating the Flory-Huggins equations for plugging in the molecular weight? Is it kg/mol or g/mol?

I want to fill a natural rubber ball a liquid that is denser than fresh water. It should approximate the density of a saturated solution of salt water. If I used un vulcanized liquid latex, would it remain stable since it was not exposed to air or heat?

According to a new research published by Polaris Market Research the worldwide Polymer Gel Market is anticipated to reach around USD 8,836 million by 2026. In 2017, the personal care segment dominated the global market, in terms of revenue. In 2017, Asia-Pacific accounted for the majority share in the global polymer gel market. The use of polymer gel in wide applications such as personal care, healthcare, agriculture, pharmaceutical, and construction among others majorly drives the growth of this market. Growing awareness regarding personal care and increasing disposable income, especially in ..read more

I'm making a polymer using aqueous acetic acid as a solvent, and need to remove the solvent after polymerization is complete, but I need to mold the polymer before it cures. Any advice on how to remove the solvent after pouring the polymer into a mold, to allow curing, would be appreciated.

Yesterday the professor teaching polymer physics was discussing the entropic elasticity of rubbers. It is evident that entropic elasticity is proportional to temperature. However, according to the time-temperature superposition, if the polymer stays in high temperature environment, it will behave like viscous fluid, and , therefore, I can't help but thinking that the modulus will accordingly decrease. So, the brobdingnagian question is why these two concepts tell opposite trends? After reading and pondering for a night, I cannot find a satisfying explaination. Can someone help me clarifying m ..read more
