摘要 |
High-density polyethylene mixed resin particles used as seed particles during seed polymerization, wherein said seed particles contain a mixed resin of 100 parts by weight of high-density polyethylene and 20 to 100 parts by weight of an ethylene copolymer; said high-density polyethylene has a density of 935 to 960 kg/m 3 and a softening temperature of 115 to 130°C; said ethylene copolymer is a copolymer of an ester-based monomer selected from an acrylic acid alkyl ester and an aliphatic saturated monocarboxylic acid vinyl, and etylene, contains 1 to 20% by weight of an ester-based monomer-derived component, and has a softening temperature of 75 to 110°C; said acrylic acid alkyl ester is selected from methyl acrylate and ethyl acrylate; and said aliphatic saturated monocarboxylic acid vinyl is selected from vinyl acetate and vinyl propionate. |
