Disclosed herein is a silicone-modified polyimide resin composition of solvent free type. The composition is suitable for use as an adhesive and a coating material which are capable of hardening upon irradiation with ultraviolet rays and/or visible rays. Also, it is saved from drooling even in the case of light filling with an inorganic compound and it is saved from bubble entrapment and nonuniformity at the time of application with heavy filling. It further exhibits good moldability due to its thixotropic properties. Moreover, it exhibits improved adhesion to polyolefin resins without impairing the past properties. Finally, it gives rise to a cured product which is not excessively hard, with a low elastic modulus, despite filling with an inorganic compound. The composition of the present invention includes components (A) to (B) listed below and is characterized by being fluid at 25° C. and free of solvent: (A) silicone-modified polyimide resin; (B) polymerizable compound; (C) polymerization initiator, (D) hydrophobic fumed silica; and (E) adhesion auxiliary agent.

The present invention relates to an acrylic processing aid and a vinyl chloride resin composition comprising the same. Specifically, the present invention relates to a core-shell structured acrylic processing aid which can play both roles as a lubricant and a processing aid at the same time by using monomers having a certain composition for the core and shell, respectively, and controlling their specific viscosity, and to a vinyl chloride resin composition comprising the same.
