Abstract: An object of the invention is to provide modified polyolefin particles which have a satisfactory amount of grafting and a sufficient molecular weight, are substantially free from gels, and exhibit excellent handleability and workability when shaped or mixed with various resins. The particles include a modified polyolefin obtained by grafting a monomer having an ethylenically unsaturated group and a polar functional group in the same molecule to a polymer including one, or two or more α-olefins selected from C2-18 α-olefins and having a melting point of not less than 50° C. and less than 250° C., the modified polyolefin particles satisfying the following requirements (1) to (3): (1) the amount of grafting x by the monomer having an ethylenically unsaturated group and a polar functional group in the same molecule is not less than 0.5 wt % and not more than 20 wt %; (2) the amount of grafting x (wt %) and the intrinsic viscosity [i](dl/g) measured in decalin at 135° C. satisfy the relation: log10[η]≧0.1−0.15x; and (3) the particles have a gel content of less than 1 wt %.
