| titleOfInvention | Initiator composition for alkaline polymerized nylon and its manufacturing method |
| abstract | PROBLEM TO BE SOLVED: To produce an initiator composition containing a diisocyanate trimer blocked with ω-lactam, which is a low-viscosity liquid that can be measured at room temperature, has a high polymerization rate of alkaline polymerization of ω-lactam, and has few health problems. Provide a method. The initiator composition for alkali-polymerized nylon of the present invention is blocked with an initiator composition containing an ω-lactam-blocked diisocyanate trimer and N-alkyl-2-pyrrolidone, or with ω-lactam. An initiator composition comprising a diisocyanate trimer, N-alkyl-2-pyrrolidone and ω-lactam. In the production method of the present invention, ω-lactam and a diisocyanate trimeric are reacted in the presence of N-alkyl-2-pyrrolidone to obtain the initiator composition of the present invention.
