Abstract: The present disclosure relates to polyamide compositions and resulting injection-molded articles that can be plated, e.g., metal coated, to form aesthetic injection-molded articles. The polyamide compositions may include from 45 wt.% to 75 wt.% of an polyamide, from 2 wt.% to 40 wt.% of an etchable filler, from 10 wt.% to 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 to injection-molded articles that are substantially free of visual defects.

Abstract: The present disclosure relates to processes for producing high molecular weight polyamides from caprolactam. In particular, the present disclosure relates to processes for adding water during Solid State Polymerization (SSP) to remove residual caprolactam to form high molecular weight polyamides, e.g., Nylon 6 and Nylon 6,6 copolymers, having low residual caprolactam monomer content. The water addition step controls the SSP process for a specific time to produce polyamides with a desired molecular weight and low residual caprolactam monomer content.

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 a process for preparing polymers using a plug flow reactor. The process includes providing an aqueous monomer solution comprising amide monomers; evaporating the aqueous monomer solution to form a concentrated monomer solution; and polymerizing the concentrated monomer solution in a plug flow reactor comprising a shell side and a tube side to form a first process fluid comprising polymers. The concentrated monomer solution flows on the shell side from the inlet to the outlet.
