  • RECYCLABLE TOOLING COMPOSITIONS AND METHODS OF THEIR MANUFACTURE AND USE
    Publication number: 20090192253
    Abstract: This invention relates generally to compositions of macrocyclic polyester oligomer (MPO), polycaprolactone, and a thermoplastic elastomer (TPE). More particularly, in certain embodiments, the invention relates to recyclable tooling compositions made from MPO, polycaprolactone, and a thermoplastic copolyester elastomer.

  • Blends containing macrocyclic polyester oligomer and high molecular weight polymer
    Publication number: 20060287440
    Abstract: The invention provides blends of macrocyclic polyester oligomer (MPO) with high-molecular-weight polymer and polymerization catalyst as friable, one-component, ready-to-polymerize materials with long shelf life. The invention also provides methods for preparation and use of the blend materials. The blends are used, for example, in the production of thermoplastics via low-pressure processes, such as rotational molding and powder coating, without modification of existing equipment. The blends are particularly useful where it is desired to exploit the ability to polymerize and crystallize MPO isothermally, but where the melt viscosity of unfilled MPO is too low for use in existing equipment.
