US 2024/0218117 A1 · POLYMERS PREPARED FROM MEVALONOLACTONE AND DERIVATIVES

Abstract

Described herein polymer precursor compounds (aka polymer building blocks) of derived from biobased compounds, and specifically biobased mevalonolactone and its related derivatives. Through oxidation these biobased precursors can be reacted to yield building blocks for (unsaturated-) polyesters, polyester polyols and polyamides, as well as precursors for glycidyl esters and omega-alkenyl esters. Through reduction, these biobased precursors can be reacted to yield building blocks for (unsaturated-) polyesters, polyester polyols, polycarbonates, as well as precursors for glycidyl ethers and omega-alkenyl ethers. Through nucleophilic ring opening and/or amidation, these biobased precursors can be reacted to yield building blocks for polyester polyols, chain-extender for polyurethanes, or polyester-amides.

wherein, independently of each occurrence,
each n is an integer from 1 to 50;
each m is an integer from 1 to 50;
each R1 is H or alkyl;
each R2 is an alkyl;
each Y is —O—, —S—, —N(H), or —N(R3);
each R3 is a linear or branched alkyl, cycloalkyl, aryl, or heteroaryl;
and
