Abstract
A thermoplastic resin composition containing a thermoplastic resin and composite particles in which a polymer graft chain is bonded to a particle surface. The thermoplastic resin composition of the present invention can be suitably used in manufactured products such as audio equipment, electric appliances, construction buildings, industrial equipment, automobile members, members of two-wheelers such as motorcycles and bicycles, and containers.
Claims20
A vibration-damping material comprising a thermoplastic resin and composite particles in which a polymer graft chain is bonded to a particle surface, wherein the graft density of the polymer graft chain is 0.001 chains/nm2 or more and 5 chains/nm2 or less.

11-13. (canceled)
A method for producing a vibration-damping material, comprising bonding a polymer graft chain to a particle surface to provide composite particles in which a polymer graft chain is bonded to a particle surface, and melt-kneading a thermoplastic resin and the composite particles, wherein the step of bonding the polymer graft chain to a particle surface is a Grafting from method comprising polymerizing the polymer graft chain from a polymerization initiating point of the particle surface, comprising the following steps 1 and 2:
- step 1:
- bonding a polymerization initiating group to a particle surface;
- and
- step 2:
- contacting particles having a polymerization initiating group on the surface and a monomer under the conditions for living radical polymerization.
15-20 (canceled)
A method for improving vibration-damping properties of a thermoplastic resin using composite particles in which a polymer graft chain is bonded to a particle surface, wherein the graft density of the polymer graft chain is 0.001 chains/nm2 or more and 5 chains/nm2 or less.
