A macromolecule comprises a ring-opened polymerized product of ?-lactone monomers of formula I: and having a structure of formula IA: wherein R1 is an alkyl group having at least 8 carbon atoms. The macromolecule may be hydroxy-terminated, and may be copolymerized with other ?-lactone monomers having different substituting groups and/or with higher lactone monomers. The macromolecule may be used as a reactant to form an alkoxysilane-terminated polymer, a polyurethane, or a (co)polyester, or may be used as an elastomeric midblock in a triblock copolymer having hard end blocks, such as polylactic acid. Such triblock systems demonstrate two discreet regions having properties similar to styrene block copolymers and are therefore suitable for use as hot melt or pressure-sensitive adhesives. In some embodiments, such triblock polymers may be entirely bio-sourced and compostable.
A hot melt adhesive composition comprises a combination of polymers including a low molecular weight semicrystalline propylene based polymer and a high molecular weight essentially amorphous propylene based polymer, both of which are prepared by using single-site catalysts, along with a wax, a hydrogenated styrene block copolymer, a tackifier, and a plasticizer. The composition has suitable viscosity ranging from 500 cP to 40,000 cP at 177°C and is useful for a variety of industrial applications where bonding of low surface energy substrates and elastic substrates is encountered, including disposable nonwoven hygienic articles. The cooled adhesive in the laminate does not feel hard but instead has a soft feel, even though the adhesive demonstrates a relatively high Shore A hardness.
