A fiber-reinforced thermoplastic composition includes a polypropylene polymer component including a low flow grade polypropylene and a high flow grade polypropylene, and a fiber reinforcement component. The fiber-reinforced thermoplastic composition is capable of being vacuum formed. In another aspect a thermoplastic composition includes a homopolymer component including polypropylene, a co-polymer component, an impact modifier, and one or more of a flame retardant component and a fiber reinforcement component. The thermoplastic composition is capable of being vacuum formed. The fiber-reinforced thermoplastic composition may be formed into an article such as an enclosure for an electrical component, and it may be chemically resistant to a medical grade cleaner.

A process for making crosslinked polyvinylpyrrolidone (PVP-P) is disclosed. Crosslinker generation, followed by polymerization of NVP, gives a polymer containing up to 4 wt. % of residual NVP. An aqueous mixture of the polymer is then heated in the presence of a protic acid at pH<4 to eliminate NVP. Finally, the PVP-P is neutralized with aqueous alkali metal hydroxide. The process generates a reduced volume of low-toxicity aqueous waste (<20 L/kg PVP-P) and gives PVP-P that meets important product specifications.

Olefins are selectively converted to epoxides by reacting with an organic hydroperoxide in the presence of a heterogeneous catalyst comprised of a carbon molecular sieve containing a Group IVA, VA, VIA, or VIIA transition metal such as molybdenum.

An improved allyl alcohol hydroformylation process and catalyst are disclosed. The process uses a catalyst system comprising a Group VIII metal carbonyl complex catalyst, a trisubstituted phosphine, a neutral Group VIII(a) metal complex cocatalyst, and optionally, a diphosphinoalkane. The process uniquely gives an enhanced linear:branched aldehyde product ratio.
