Abstract: A method of manufacturing a heat dissipation sheet including preparing a preliminary sheet including a matrix-forming component, a crosslinking agent, and a heat dissipation filler, and crosslinking the matrix-forming component included in the preliminary sheet and thus obtaining a heat dissipation sheet. The heat dissipation sheet manufactured has remarkably excellent heat dissipation properties because it contains a high content of heat dissipation filler. Due to the material properties of the matrix-forming component and the crosslinking of the matrix-forming component and the resulting matrix formation, the occurrence of cracking, shrinkage, pore formation, thickness change, and the like is minimized or prevented, and excellent flexibility can be attained. Moreover, since processability is improved through processes such as cooling when manufacturing the heat dissipation sheet, productivity is excellent, and the sheet can be suitable for mass production.

Abstract: A method of preparing a graft copolymer includes a step of performing coagulation by adding an acid coagulant to 100 parts by weight (based on solids) of graft copolymer latex prepared by graft-polymerizing an aromatic vinyl compound and a vinyl cyanide compound onto conjugated diene rubber latex; and a step of performing coagulation once more by adding a salt coagulant thereto. In a resulting graft copolymer, coagulation efficiency may be improved and the gloss of the prepared graft copolymer may be increased. In addition, since a b-value measured using a Hunter lab colorimeter and a b-value measured after being left at 250° C. for 15 minutes are low, the graft copolymer may have excellent color characteristics. In addition, since heating loss is low and scorch time is long, the graft copolymer may have excellent processing characteristics.
