Miscible blends of epoxy-extended polyetherester resins and commercial polymer resins are disclosed. Thermosets from the resin blends offer high-performance physical properties at a reduced cost compared with that of commercial high-performance resins. The thermosets have improved physical properties, including excellent water resistance, compared with many commercial systems. Resin blends of the invention are readily thickened, and are thus useful for SMC applications.

Microemulsion cleaner compositions are disclosed. The cleaners comprise a terpene, a secondary or tertiary C.sub.4 -C.sub.5 alcohol, a surfactant, and water. Compared with commercial formulations, cleaners of the invention are low in water, high in hydrocarbon, and have excellent degreasing capability. The secondary or tertiary C.sub.4 -C.sub.5 alcohol coupling solvent, compared with other alcohols, significantly reduces the amount of surfactant required to produce a stable, effective microemulsion cleaner. The compositions are particularly valuable as metal degreasers.

A process for the separation of ditertiary butyl peroxide form tertiary butanol is provided which includes the step of dehydrating the tertiary butanol to isobutylene and water.

Purification of ditertiary butyl peroxide

The present invention provides a process the production of dialkyl peroxides by reaction of an alcohol and/or an olefin with an organic hydroperoxide, using an acidic resin catalyst, especially a highly cross-linked hydrophobic acidic resin catalyst.
