  • Resin composition whose lubricity under wet conditions is maintained
    Patent number: 10000629
    Abstract: Provided is a resin composition that will suffer from little drop of lubricity and will offer good touch feeling even if it is used repeatedly. A resin composition superior in lubricity and touch feeling is produced by melt-mixing a water-soluble polyethylene oxide having a viscosity average molecular weight of 1,000,000 to 6,000,000, a modified polyalkylene oxide obtainable by reacting a polyalkylene oxide, a diol compound, and a diisocyanate compound together, and a thermoplastic resin together.
    Type: Grant
