METHODS FOR USING ADHESIVES WHICH ARE THERMALLY-REVERSIBLE AND TEMPERATURE-SENSITIVE
Adhesives comprising a silyl-terminated polyether and a tackifying resin provide a considerably reduced tack at relatively slight increases in temperature, undergo purely adhesive failure at such increased temperatures, and have reversible properties (i.e., such properties are substantially retained upon cooling). Such adhesives may be used to reversibly bond a first substrate surface coated with the adhesive to a second substrate surface by adhering the substrate surfaces together at a first temperature; heating the adhesive to a second temperature at least about 20° C. above the first temperature and below the thermal degradation temperature; and separating the substrate surfaces from one another at the second temperature, wherein the adhesive comprises the cured product of a silyl-terminated polyether and a tackifier. Such adhesives may also be cleanly transferred from to a different substrate at such elevated temperatures. Such adhesives may be used for tapes suitable for easy removal at elevated temperatures.

A process for manufacturing the film comprises flat sheet coextrusion of composition (a) and of compositions (b) and (c) at a temperature of between 150° C. and 250° C. The multilayer film can be used for the manufacture of resealable packaging.

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.
