ABSTRACT:
Molding compositions useful for molding water-extended hydrophilic articles are provided which are tough, soft and form-stable and comprise, generally, an amide-endcapped hydrophilic alkylene oxide polymer, a crosslinking agent, water, and a filler. The composition is cured by means of an acid catalyst. The compositions are useful in the preparation of denture liners which exhibit excellent adhesion to denture plates and provide structural stability, toughness and softness.
