Resin composition whose lubricity under wet conditions is maintained

Abstract

Provided is a resin composition which has excellent lubricity and a good touch feeling under wet conditions and suffers from little deterioration in the lubricity or the good touch feeling even if used repeatedly, and is excellent in flexibility. More specifically, the resin composition contains 100 parts by mass of a water-absorbing polymer and 60 to 500 parts by mass of a thermoplastic resin that has a type D durometer hardness (HDD) of 10 to 60.

1 . A resin composition comprising 100 parts by mass of a water-absorbing modified polyalkylene oxide and 60 to 500 parts by mass of a thermoplastic resin having a type D durometer hardness (HDD) of 10 to 60. 
     
     
         2 . The resin composition according to  claim 1 , wherein the water-absorbing modified polyalkylene oxide is a modified polyalkylene oxide obtained by reacting a polyalkylene oxide compound, a diol compound and a diisocyanate compound. 
     
     
         3 . The resin composition according to  claim 1 , wherein the water-absorbing modified polyalkylene oxide has a water absorption ability of 10 to 40 [g/g]. 
     
     
         4 . The resin composition according to  claim 1 , wherein the water-absorbing modified polyalkylene oxide has a proportion of water-soluble component of 5 to 30% by mass. 
     
     
         5 . The resin composition according to  claim 1 , wherein the thermoplastic resin is an ethylene/vinyl acetate copolymer, an ethylene/acrylic acid copolymer, an ethylene/ethyl acrylate copolymer or a combination thereof. 
     
     
         6 . The resin composition according to  claim 2 , wherein the water-absorbing modified polyalkylene oxide has a water absorption ability of 10 to 40 [g/g]. 
     
     
         7 . The resin composition according to  claim 2 , wherein the water-absorbing modified polyalkylene oxide has a proportion of water-soluble component of 5 to 30% by mass. 
     
     
         8 . The resin composition according to  claim 3 , wherein the water-absorbing modified polyalkylene oxide has a proportion of water-soluble component of 5 to 30% by mass. 
     
     
         9 . The resin composition according to  claim 2 , wherein the thermoplastic resin is an ethylene/vinyl acetate copolymer, an ethylene/acrylic acid copolymer, an ethylene/ethyl acrylate copolymer or a combination thereof. 
     
     
         10 . The resin composition according to  claim 3 , wherein the thermoplastic resin is an ethylene/vinyl acetate copolymer, an ethylene/acrylic acid copolymer, an ethylene/ethyl acrylate copolymer or a combination thereof. 
     
     
         11 . The resin composition according to  claim 4 , wherein the thermoplastic resin is an ethylene/vinyl acetate copolymer, an ethylene/acrylic acid copolymer, an ethylene/ethyl acrylate copolymer or a combination thereof.
