PURPOSE: To obtain a molded product having excellent mechanical strengths and formed from an aqueous feedstock solution having improved storage stability and prepared by mixing an alkali metal acetate with an acetoacetate-group- containing PVA resin containing acetic acid of a specified amount or below.

CONSTITUTION: This molded product is made from an acetoacetate-group- containing PVA resin containing 2wt.% or below alkali metal acetate (A) and 5wt.% or below acetic acid and having an A/B weight ratio of 0.01-100. It is desirable that the product is made from an acetoacetate-group-containing PVA resin containing 0.01-0.3wt.% component A and 0.001-3wt.% component B and having an A/B weight ratio of 0.1-10. An aqueous solution used in the production of the molded product has excellent storage stability, and the obtained molded product has not deteriorated mechanical properties. Further, even when the aqueous solution contains a conventionally used crosslinking agent, it has a small change in viscosity, good storage stability and excellent moldability.
