Abstract: A process for the preparation of a compound having the structure of Formula (I) wherein A, R1, R2, R3, Y and Z are as defined in the disclosure. The process includes reacting a heterocyclic amine with a monoaldehyde or a dialdehyde in a pH range of from about 8 to 14 and then quaternizing the so-reacted heterocyclic amine with an alkylating agent at a pH of not less than about 2. The use of a pH control substantially prevents formation of an undesirable protonated intermediate.

Abstract: Polyamide contains 0.05-3% esters of amides of 10-20C atom linear alkane mono-carboxylic acids and 1-12C atom aliphatic alcohols or 2-12C atom aliphatic diamines. These products are transparent and glass-clear. As example a mixture of 99.9% polycaprolactam and 0.1% octyl palmitate after extrusion has a relative light transmission value of 35, while threads with 0 and 0.05% additives have values of 9 and 28 respectively.
