Abstract

<p>α-Pinene was introduced into hydrolysable polymers by melt blending method. α-Pinene was released over 10 to 20 days by hydrolysis of polymers in acidic aqueous solution. Release rate of α-pinene increased with an increase in hydrophilicity of the polymer; that is, hydrophilicity accounts for its enhanced degradability. However, mechanical strength of the polymers decreased up to 20 to 30 % of their initial strength by incorporating of α-pinene into polymers. </p>
