DEGRADABLE POLYMER COMPOSITION FOR USE IN DOWNHOLE TOOLS AND METHOD OF MANUFACTURING
A chemical composition for a degradable polymeric material includes an isocyanate terminated polyester prepolymer, including prepolymer units as a main chain with a plurality of isocynanates at ends of the main chain, and a cross-linking agent. The isocyanate terminated polyester prepolymer has a structural formula as follows:ONC—R″—NH—[—CO—R—R″′-]n-NH—R″—CNO,wherein R″′ is selected from a group consisting of —O— and —CO—O—R′—O—,wherein R, R′ and R″ are an aryl group or alkyl group and wherein n is a number of prepolymer units corresponding to length of the main chain. The composition degrades at a rate and at a delay depending on temperature and the composition for a component of a downhole tool. The composition has strength and elasticity for a component of a downhole tool.
