Patent ID: 7122584

Claim:
A process for producing a soft resin pellet, comprising the steps of contacting at least one liquid (B) with pellets of at least one soft resin (A) to coat the surface of said pellets with said liquid (B), and contacting said coated surface of said pellets with fine powder (C), wherein said at least one liquid (B) has a kinematic viscosity at 25° C. ranging from 0.5 to 100,000 cSt (centistokes) and a surface tension at 25° C. ranging from 10 to 50 dyn/cm, and said at least one fine powder (C) has an average particle diameter of not more than 50 μm, said at least one soft resin (A) being selected from the group consisting of the resins (i)–(v) below and having a tensile modulus determined according to ASTM D-658 not higher than 1600 MPa: (i) ethylene/α-olefin in copolymers produced by copolymerizing ethylene and at least one α-olefin of 3–20 carbon atoms, (ii) propylene/α-olefin copolymers produced by copolymerizing propylene and at least one α-olefin of 2 or 4–20 carbon atoms, (iii) unsaturated olef in copolymers produced by copolymerizing randomly ethylene, at least one α-olefin of 3–20 carbon atoms, and at least one monomer selected from the group consisting of conjugated diene monomers represented by the chemical formula below and nonconjugated polyene monomers: wherein R 1 and R 2 are independently a hydrogen atom, an alkyl group of 1–8 carbon atoms, or an aryl group, and at least one of R 1 and R 2 is a hydrogen atom, (iv) ethylene/vinyl acetate copolymers containing vinyl acetate at a content ranging from 5 to 40% by weight, and (v) cycloolefin resins.
