Document Type and Number:
Japanese Patent JP7216628
Kind Code:
B2
Abstract:
To provide a resin modifier hardly generating delamination even when blended with a thermoplastic resin, and capable of modifying abrasion resistance, slidable characteristic and creak while maintaining general physical properties sufficiently.SOLUTION: There is provided a graft copolymer (A) obtained by graft polymerization of total 20 to 70 pts.mass of an aromatic vinyl monomer (b) and, if needed, other vinyl monomer (c) copolymerizable with the aromatic vinyl monomer (b) in presence of 30 to 80 pts.mass of an ethylene polymer (a) (total of (a), (b) and (c) is 100 pts.mass), in which the ethylene polymer (a) has density of 0.900 g/cmor more and less than 0.966 g/cm, number average molecular weight of 10,000 to 50,000, molecular weight distribution of 5 to 15, and percentage of molecular weight of 10,000 or less of 5.5% or more.SELECTED DRAWING: None
