Abstract

The polyester based polymer composition includes a polyester, a metal oxide, and a metal hydroxide. The polymer composites contains the metal oxide and a metal hydroxide made from melting blending has good mechanical property as well as greater degradability after a required time in the higher temperatures and moisture of downhole conditions. The reinforced polymer composites with glass fibers, and the metal oxide and metal hydroxide made from melting blending has higher mechanical property as well as greater degradability after a required time in the higher temperatures and moisture of downhole conditions. The polymer composites made from melting blending have the required mechanical properties and the degradability so that the polymer composites can be used for degradable or dissolvable component of a downhole tool.
