Abstract: A hydrolysis resistant polyamide composition comprising from 50 wt% to 80 wt% polyamide polymer having a theoretical amine end group content of at least 55 µeq/gram; and from 25 wt% to 60 wt% glass fibers. The weight ratio of polyamide polymer to glass fibers ranges from 0.5:1 to 4.0:1. The polyamide composition comprises less than 0.06 wt% copper; and/or from 1 ppb to 0.24 wt% non-copper metal halide compound. The polyamide composition, when hydrolysis aged for 500 hours at 130°C, demonstrates an impact resilience greater than 40 kJ/m2, as measured at 23C.

Abstract: The present disclosure relates to fluid bed processes that utilize silica particles as a fluidization aid. The process comprises reacting one or more reactants in a reactor comprising a fluid bed to form a product. The fluid bed comprises a catalyst composition comprising a catalyst and an inert additive composition comprising silica particles from 0.5 wt% to 30 wt%, based on the total weight of the catalyst composition. The silica particles are discrete, inert particles that are mixed with the catalyst in the fluid bed.

Abstract: The present disclosure relates to polyamide compositions and resulting injection-molded articles that can be plated, e.g., metal coated, to form structurally aesthetic injection-molded articles. The polyamide compositions may include from 40 wt.% to 80 wt.% of a polyamide, from 0.5 wt.% to 40 wt.% of an etchable filler, from 5 wt.% to 30 wt.% of glass fiber, optionally less than 40 wt.% of a semi-structural mineral, and optionally from 0.1 wt.% to 13 wt.% of additive. The polyamide composition imparts very good surface appearance and excellent mechanical properties to injection-molded articles that are substantially free of visual defects.
