Abstract
PURPOSE: To obtain an olefin/vinyl acetate copolymer hydrolyzate which is stable against heat, resistant to discoloration and easy to heat-mold, by adding a specific amount of acetic acid and sodium acetate to an olefin/vinyl acetate copolymer hydrolyzate.
CONSTITUTION: To a hydrolyzate of an olefin/vinyl acetate copolymer having a C5-olefin content of 5W95mol%, are added 0.003W1wt% of (B) sodium acetate and (A) acetic acid in an amount satisfying the equation, wherein [I] is the weight percentage of B contained in the copolymer hydrolyzate or its derivative, [II] is the MW of B, [III] is the weight percentage of A contained in the copolymer hydrolyzate or its derivative and [IV] is the MW of A. When the acetic acid content is lower than that given by the equation, the copolymer hydrolyzate, upon heating, discolors pale yellow to pink, and lowers in melt miscosity. This causes trubles in heat- molding. When the sodium acetate content is equal to or higher than 1wt%, the discoloration and decomposition of the copolymer hydrolyzate are accelerated, when the hydrolyzate is heated.
