Hello,
I would like receive some information about polyacetal. Any kind of info will be very helpful for my chemistry graduation project (e.g. website links, texts, books...).
Thank you. Rita

Polyacetal is often synthesized using cationic ring-opening polymerization. Polyacetal is useful for making graft or block copolymers with a variety of uses, including intercalation, pH sensative hydrogels, and biocompatible materials.

Hallo Prof Wissmann,
My name is Ana Soares, I am mechanical engineering from Brazil. I work with FEM and presently I need to simulate a polipropyline component. However, my FEM program ask for E, modulus of elasticity. Unfortunately, I could just find the "flexural modulus" (1200 MPa, according to the supplier) what seems to be very similar to modulus of elasticity. Is there any relation between both of them? Also, this component is subimitted to a temperature of 75 C. How does the flexural modulus changes with temperature? Thank you! Ana Soares
