Question
Polymerization of liquid mixtures containing this functional group can be delayed using “latent” reagents such as dicyandiamide powder. Most polymers named for this functional group derive from the BPA-containing monomer BADGE. Monomers of this functional group undergo anionic ROP to form polymers like PPO and PEO. A reaction that produces this functional group proceeds via a “butterfly mechanism.” A class of thermosets named for this functional group can be mixed with hardener to form quick-curing adhesives and coatings. This functional group can be synthesized by treating halohydrins with a base or reacting alkenes with a peroxy-acid like mCPBA. For 10 points, ethylene oxide is the simplest example of what highly-strained functional group consisting of a three-membered cyclic ether? ■END■
