Abstract:
1. A method of preparing an thermoplastic resin composition comprising: obtaining a crosslinked softening agent composition by blending and heat treating the components comprising: (a) 100 parts by weight of at least one non-aromatic hydrocarbon softening agent for rubber; (b) 0.1 to 10 parts by weight of an organic peroxide; and (c) 0.1 to 50 parts by weight of a crosslinking aid, wherein the weight ratio of component (b) to component (c) is 1 or less and components (a)-(c) are blended and heat treated in the absence of any thermoplastic resins; and blending the crosslinked softening agent composition with 1 to 1500 parts by weight of a thermoplastic resin relative to 100 parts by weight of the crosslinked softening agent composition.
