PROBLEM TO BE SOLVED: To provide an ethylenic copolymer pellet with high anti-blocking property of mutual pellets, and a hot-melt adhesive with high heat stability. SOLUTION: This ethylenic copolymer pellet comprises 0.01 to 1.0 pt.wt. of a lubricant with 60 to 180°C melting point to 100 pts.wt. of the ethylenic copolymer pellet, and has surface roughness Ra according to JIS B0601 of 1.0 to 2.5μm. This hot-melt adhesive uses this ethylenic copolymer pellet. COPYRIGHT: (C)2003,JPO |
