Abstract: A composition having a recycle content value is obtained by reacting a recycle content feedstock to make a recycle content alpha olefin or by deducting from a recycle inventory a recycle content value applied to an alpha olefin composition. At least a portion of the recycle content value in the feedstock or in an allotment obtained by an alpha olefin manufacturer has its origin in recycled waste and/or pyrolysis of recycled waste and/or in thermal steam cracking of recycle content pyoil.

Abstract: Polyesters having both α,β-unsaturated groups and moieties containing activated methylene or methine groups, such as those of beta-ketoester and malonate, are curable in the presence of a base catalysts to form crosslinked networks. Formulations based on such polyesters are suitable for use in coatings and cure at temperatures less than 230° C. without the use of isocyanates.
