Polycarbonate polymers comprising non-aromatic cyclic groups bonded with carbonate linking groups are described. A portion of the non-aromatic cyclic groups comprise a substituent having siloxane repeat units. Representative formulas of the substituents having siloxane repeat units include CH.sub.2CH.sub.2Si(R.sup.4).sub.2(OSi(R.sup.4).sub.2R.sup.5, and CH[Si(R.sup.4).sub.2(OSi(R.sup.4).sub.2).sub.mR.sup.5]CH.sub.3; wherein m is the number of siloxane repeat units; and R.sup.4 and R.sup.5 are independently alkyl, aryl, aralkyl or aralkylene. The polycarbonate polymer C typically comprises a high concentration of carbonate linking group, for example in an amount of at least 85 or 90 mol % or greater N based on the total linking groups of the polymer. Also described are compositions comprising the polycarbonate polymer and methods of making.

A macromolecule comprises a ring-opened polymerized product of -lactone monomers of formula I: ##STR00001## and having a structure of formula IA: ##STR00002##
wherein R.sub.1 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.
