ABSTRACT:
A silated polyvinyl alcohol with a degree of substitution (D.S.) between 0.005 and 0.5 is prepared by reacting polyvinyl alcohol with a silating agent. Preferred silating agents are 3-glycidoxypropyltrimethoxysilane or vinyltrimethoxysilane. An alkali metal or ammonium salt of the silated polyvinyl alcohol can self-crosslink in the presence of atmospheric carbon dioxide to form a water resistant film which is soluble in caustic.
