Claim 2
Dependent Claim
79 words
A relatively water-stable composition comprising a water-curable thermoplastic polymer having hydrolyzable, pendant moieties of the formula: ##STR11## wherein R is methyl, ethyl or propyl and each V is a hydrocarbon radical having 1 to 18 carbon atoms inclusive or --OR) wherein R is as previously defined; at least a stoichiometric amount of a primary monohydric alcohol having at least 4 carbon atoms or a secondary monohydric alcohol having at least 3 carbon atoms; and an organo titanate esterification catalyst.
Claim 3
Dependent Claim
81 words
A relatively water-stable composition comprising a water-curable thermoplastic polymer having hydrolyzable, pendant moieties of the formula: ##STR12## wherein R is methyl, ethyl or propyl and each V is a hydrocarbon radical having 1 to 18 carbon atoms inclusive or --OR) wherein R is as previously defined; at least a stoichiometric amount of a primary monohydric alcohol having 4 to 18 carbon atoms inclusive or a secondary monohydric alcohol having 3 to 18 carbon atoms inclusive; and an organo titanate esterification catalyst.
