A process comprising contacting a polyhydric phenol or a polyaliphatic alcohol with an epihalohydrin in the presence of a catalyst comprising a Schiff base metal complex is disclosed.

Epoxy resin production

A process of contacting an alkylene oxide with 2-methoxy-1-propanol (PM1) in the presence of an oligomeric Schiff base metal complex catalyst is disclosed. Further, a process involving contacting an alkylene oxide with an alkyl alcohol using an oligomeric Schiff base metal complex as a catalyst is also disclosed. Additionally, novel compositions which can be used as catalysts in processes involving the contacting of an alkyl alcohol with an alkylene oxide are also disclosed.

Alkoxylation processes and catalysts therefor

Embodiments of the present disclosure include polycyclopentadiene compounds represented by Formula (I): in which each X is either a hydrogen or a cyano group (N&#x2261;C&#x2014;), n has an average value from zero to 20; each m independently has a value of zero to 3; p has a value of zero to 20; each R is independently a halogen, a nitrile group, a nitro group, an alkyl group, an alkoxy group, an alkenyl group, or an alkenyloxy group, where the alkyl group, the alkoxy group, the alkenyl group, and the alkenyloxy group each independently contain 1 to 6 carbon atoms; and each Q is independently hydrogen or an alkyl group containing 1 to 6 carbon atoms. Embodiments of the present disclosure also include a curable composition that includes the polycyclopentadiene compound(s) of Formula (I) and a curing amount of a resin or a catalyst amount of a catalyst and/or a cure accelerating amount of an accelerating agent.
