摘要： 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.
摘要翻译：本发明提供大环聚酯低聚物（MPO）与高分子量聚合物和聚合催化剂的混合物，其具有长寿命的易碎，单组分，即用型聚合材料。本发明还提供了制备和使用共混材料的方法。混合物例如用于通过低压方法生产热塑性塑料，例如旋转模塑和粉末涂料，而不改变现有设备。在需要利用MPO等温聚合和结晶MPO的能力的情况下，共混物特别有用，但未填充的MPO的熔融粘度太低而不能用于现有设备。

摘要： A water slurry process is used to prepare a prepreg and to manufacture articles from macrocyclic polyester oligomers. In one embodiment, a process for preparing a water suspension of macrocyclic polyester oligomers includes the steps of contacting a macrocyclic polyester oligomer and a polymerization catalyst with water and a surfactant, and mixing the macrocyclic polyester oligomer and polymerization catalyst with water and the surfactant thereby forming a suspension. In another embodiment, a process for impregnating macrocyclic polyester oligomers for polymerization includes the steps of providing a suspension of a macrocyclic polyester oligomer and a polymerization catalyst in water, applying the suspension to a base material, drying to remove water from the suspension, and pressing the dried suspension to a desired form. In yet another embodiment, a composition of macrocyclic polyester oligomer includes a macrocyclic polyester oligomer, a polymerization catalyst, and water. In yet another embodiment, a process for polymerizing macrocyclic polyester oligomers includes the steps of mixing a blend material having a macrocyclic polyester oligomer and a polymerization catalyst with water to form a mixture, applying the mixture to a base material, drying to remove water, heating to polymerize the macrocyclic polyester oligomer, and pressing the polymerized macrocyclic polyester oligomer to a desired form.

摘要： The invention provides mixtures of macrocyclic polyester oligomer (MPO) and graphite, as well as methods for their preparation and use. Exfoliated graphite can be homogeneously dispersed in molten MPO without excessive increase in melt viscosity, and the MPO-graphite mixture can be polymerized to form electrically conductive polymer nanocomposites. In one embodiment, the invention provides mixtures of MPO with exfoliated graphite. In another embodiment, the invention provides a mixture of MPO, exfoliated graphite, and polymerization catalyst as a one-part, ready-to-polymerize material with a long shelf life. The one-part material can be used, for example, in the manufacture of parts without modification of existing processing equipment.

摘要： The instant invention provides a substantially flame retardant composition comprising: (a) a thermoplastic polyester and copolyester material, a halogenated organic fire retardant, antimony oxide, organo clay, and a fluorocarbon polymer. Also provided are compositions comprising glass fibers and stabilizers. The combination of the organo clay and the fluorocarbon polymer exhibits a synergistic effect on the fire retardant properties of the instantly claimed composition. This synergistic effect helps reduce the amount of the halogenated organic fire retardant in the instantly claimed flame retardant composition.
