A thermoplastic resin composition comprises a thermoplastic resin (A) having a solubility parameter delta of at least 9.5 cal<1/2>cm<-3/2> in which a modifier (B) having a solubility parameter delta of not higher than 8.5 cal<1/2>cm<-3/2> is dispersed to form a dispersion, characterized by containing a dispersibility improver (C) comprising a silicon-containing polyacetal copolymer prepared by bonding 0.01 to 30 wt.% of a terminal-reactive silicone oil of the following general formula [I]: <CHEM> wherein R1 represents an alkyl or phenyl group, R2 represents a divalent organic group, X represents a group selected from the group consisting of -NH2, -OH, <CHEM> -R4OH, -R5COOH, -R6COOR7, -R8 and -OR9, R3 represents a divalent organic group, R4 to R6 each represent an alkylene group having 1 to 10 carbon atoms, R7 to R9 each represent an alkyl group having 1 to 10 carbon atoms and n represents a number of 5 to 10. |
