摘要:Various embodiments provide random copolyimides that may possess the mechanical, thermal, chemical and optical properties associated with polyimides yet achieve a low energy surface. In various embodiments, the copolyimides may be prepared using a minor amounts of a diamino terminated fluorinated alkyl ether oligomer and a diamino terminated siloxane oligomer. The various embodiments include processes for making the copolyimides containing fluorine and silicon surface modifying agents and anisotropic coatings and articles of manufacture from them. Thus the coatings and articles of manufacture made with the copolyimides of the various embodiments may be characterized as having an anisotropic fluorine and silicon composition and low surface energy.

摘要:A composition having a mixture of the below compounds having a mole ratio of at least 1:20. Ar 1 and Ar 2 are independently selected aromatic groups. A composition comprising phthalonitrile compounds that comprise at least 5 mol % of the first compound below. n nA method of: providing a solution of a dichloroaromatic compound having an electron-withdrawing group bound to each aromatic ring containing one of the chloride groups; a dihydroxyaromatic compound or anion thereof; an organic transition metal complex or a transition metal salt; an alkaline hydroxide base; and a solvent; and heating the solution to a temperature at which the dichloroaromatic compound and the dihydroxyaromatic compound react to form a dimetallic salt of an aromatic ether oligomer. The molar ratio of the dihydroxyaromatic compound to the dichloroaromatic compound is greater than 2:1. Water formed during the heating is concurrently distilled from the solution.
