| titleOfInvention | Lactam oligomer composition, method for producing the same, catalyst, and method for producing polycaprolactam |
| abstract | (57) [Abstract] (Correction) [PROBLEMS] A lactam oligomer composition having a high polymerization rate into a polyamide. SOLUTION: ε-caprolactam, a chain oligomer having one or more structural units represented by formula I, zero or more structural units represented by formula II and zero or more structural units represented by formula III. , And a lactam containing a cyclic oligomer which is not an essential component but has two or more structural units represented by the formula I, zero or more structural units represented by the formula II and zero or more structural units represented by the formula III. An oligomer composition, The concentration of the chain oligomer in the composition was 8 × 10 based on 1 g of the total amount of caprolactam, chain oligomer and cyclic oligomer. It is -6 mol or more, and the ratio of the caprolactam dimer, which is a cyclic oligomer, to the total sum of caprolactam, chain oligomers and cyclic oligomers is 0.3% by weight or less. (In the formula, R 1 represents a divalent hydrocarbon group having 2 to 18 carbon atoms, and R 2 represents a divalent hydrocarbon group having 2 to 20 carbon atoms.) |
