HOT MELT ADHESIVE COMPOSITIONS BASED ON POLY(ALPHA-METHYL-BETA-PROPIOLACTONE) POLYMERS OR DERIVATIVES AND METHODS FOR USING THEM
A hot melt adhesive composition comprises a polymer comprising poly(α-methyl-β-propiolactone) (PMPL) or a derivative thereof, wherein the PMPL is polymerized from a plurality of (R)-α-methyl-β-propiolactone monomers and a plurality of (S)-α-methyl-β-propiolactone monomers, wherein the ratio of (R):(S) monomers is from about 90:10 to about 10:90. Changing the (R):(S) ratio impacts the isotactic diad fraction and consequently the crystallinity and thermomechanical properties of the resulting PMPL. The PMPL may be hydroxyl-terminated, with the residue thereof serving as the elastomeric B block in an A:B:A triblock copolymer having hard end A blocks, such as a residue of polylactic acid. The PMPL diol may also be used as a reactant to form an alkoxysilane-terminated polymer, a polyurethane, or a (co)polyester. In some embodiments, such triblock polymers may be entirely bio-sourced and compostable.
