Title:
GRAFT COPOLYMER, THERMOPLASTIC RESIN COMPOSITION AND MOLDED ARTICLE OF THE SAME
Document Type and Number:
Japanese Patent JP2019026666
Kind Code:
A
Abstract:
To provide a graft copolymer that is suitable as a material of a thermoplastic resin composition capable of obtaining a molded article excellent in color developing property and scratch resistance, and a thermoplastic resin composition containing the graft copolymer and a molded article of the same.SOLUTION: A graft copolymer is obtained by polymerization of a vinyl monomer component (m1) in the presence of an ethylene-α-olefin copolymer (a) having a volume average particle diameter of 0.15-0.30 μm. In the graft copolymer, when the ethylene-α-olefin copolymer (a) is measured at 30°C by pulse NMR, an average value (T2ave.) between a component (α) with the longest spin-spin relaxation time and a component (β) with the second longest spin-spin relaxation time represented by following expression (1) is 270 μs or less. Expression (1): 1/T2ave.={AM(X)/T2(X)+AM(Y)/T2(Y)}/{AM(X)+AM(Y)}.SELECTED DRAWING: None
