AMPHIPHILIC BLOCK COPOLYMERS AND MACHINE DISHWASHING DETERGENTS CONTAINING THESE

摘要

It is possible to prevent or at least mitigate discolouration of plastics tableware during machine dishwashing by using amphiphilic block copolymers of -An-Bm- type, where A represents the hydrophilic monomer unit of the hydrophilic block An and B represents the hydrophobic monomer unit of the hydrophobic block Bm and a diene serves as monomer for the hydrophobic monomer unit B.
