    摘要: The present invention provides thermoplastic hydroxy-functional polyesters. The polyesters have at least 10 sequential units, wherein the sequential units consist of units selected from units represented by the following formula (1) and units represented by the following formula (2); Wherein each of R1 independently represents hydrogen or a substituted or unsubstituted homoalkyl or heteroalkyl group; each of R2 independently represents hydrogen or a substituted or unsubstituted homoalkyl or heteroalkyl group; each of R3 independently represents hydrogen or a substituted or unsubstituted homoalkyl or heteroalkyl group; Each of R4 independently represents a substituted or unsubstituted homoalkyl or heteroalkyl group; and said moiety having no fewer than 1 unit represented by formula (1) and no fewer than 1 unit represented by formula (2). The present invention further provides processes for making hydroxyfunctional polyesters, such as polymerizing epoxidized fatty acids in the presence of an onium salt, and compositions and articles that include or are derived from the hydroxyfuntional polyesters

    摘要: The precipitation of iron and aluminum from their solutions in strong acids, eg. 18% HCl and 25% H.sub.2 SO.sub.4, is accomplished by adding to the acid solution certain organic aminophosphonic acids in which at least 50% of the amine hydrogens have been substituted with methylenephosphonic acid groups. Particularly preferred compounds are the methylenephosphonic acid derivatives of ammonia and polyalkylenepolyaminepoly(methylenephosphonic acids). The completely phosphonomethylated derivatives are most preferred.

    摘要: Disclosed are thermosettable compositions comprising (A) an epoxy resin such as the diglycidyl ether of bisphenol A; (B) boron trifluoride complexed with a primary, secondary or tertiary amine such as monoethanolamine and (C) at least one cyclic or acyclic phosphazene having at least one pendant ##STR1## group wherein Z is an alkyl or an aryl group such as hexa(n-propylamino)cyclotriphosphazene.When cured, these compositions have an increased glass transition temperature (Tg) value as compared to a similar composition without the phosphazene compound.These compositions are useful in potting compositions, wet lay-up and pre-impregnated laminate, adhesive, molding, coating, casting, encapsulation, filament winding and transfer molding applications.
