Title:
Terminal-modified-polyamide resin, its manufacturing method, and a manufacturing method of a cast
Document Type and Number:
Japanese Patent JP5928662
Kind Code:
B2
Abstract:
The present invention addresses the problem of providing a high molecular weight, terminal modified polyamide resin having a low melt viscosity and excellent molding processability. The problem is solved by a terminal modified polyamide resin having a relative viscosity (·r), as measured at 25°C in a 98% sulfuric acid solution at a resin concentration of 0.01 g/ml, of 2.1 to 10, the resin comprising 0.05 to 4.5% by mass of a terminal structure represented by general formula (I):
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ-X-(R 1 -O) n -R 2 €ƒ€ƒ€ƒ€ƒ€ƒ(I)
wherein n ranges from 2 to 100; R 1 represents a hydrocarbon group of 2 to 10 carbon atoms; R 2 represents a hydrocarbon group of 1 to 30 carbon atoms; -X- represents - NH- or -N(CH 3 )-; and n R 1 s in the general formula (I) may be the same or different.
