PURPOSE: A composition for an acrylic reinforcing agent for PVC is provided to reduce the time and the effort for separately adding an impact reinforcing agent and a processing aid and to improve surface gloss and low temperature impact resistance. CONSTITUTION: A composition for an acrylic reinforcing agent for PVC comprises (a) 50-80 weight% of acrylic impact reinforcing agent, (b) 10-30 weight% of a first processing aid with average molecular weight of 2,500,000-3,000,000, (c) 5-20 weight% of a second processing aid with average molecular weight of 800,000-1,500,000, and (d) 5-20 weight% of a third processing aid with average molecular weight of 50,000-300,000.
