Abstract:
A resin fine powder which consists of a 4-methyl-1-pentene polymer that exhibits a limiting viscosity [η] of 1.0×10−2 to less than 3.0 dl/g as determined in decalin at 135° C. and which has a median particle diameter [D50] of 1.0×10−1 to 5.0×10 μm; and a composition which comprises the resin fine powder and at least one sinterable powder selected from the group consisting of metal powders and ceramic powders.
