Title: TERMINALLY MODIFIED POLYAMIDE RESIN
Abstract:
This terminally modified polyamide resin has a terminal structure represented by general formula (I), wherein the terminal structure represented by general formula (I) is contained at a quantity of 1-10 mass% relative to 100 mass% of the terminally modified polyamide resin, the weight average molecular weight / content [mass%] ratio of the terminal structure represented by general formula (I) is 6,000-20,000, and the melt viscosity at a temperature corresponding to melting point+60ºC and at a shear rate of 9728 sec-1 is 0.1-8 Pa·s. General formula (I): -X-(R1-O)m-R2 (I) (In general formula (I), m denotes the range 2-100. R1 denotes a divalent hydrocarbon group having 2-10 carbon atoms, and R2 denotes H or a monovalent organic group. -X- denotes -NH-, -N(CH3)-, -(C=O)- or -CH2-CH(OH)-CH2-O-. The number m of R1 groups contained in general formula (I) may be the same as, or different from, each other.)
