    摘要： The invention relates to the formation of isoimides from amic acids, especially polyisoimides by a novel process in which polyimides are first converted to polyamic acids and then contacted with an isoimidizing agent. An acyl halide of a heterocyclic nitrogen compound or an acyl halide of a heterocyclic sulphur compound can be used as the isoimidizing agent. The isoimidization may also be carried out in the presence of a compound containing a heterocyclic nitrogen especially a solvent containing a heterocyclic nitrogen.The invention is especially applicable to conducting nucleophilic addition reactions on the surface of polyimides where the surface has been converted to a polyamic acid or on the surface of polyamic acid materials followed by isoimidization and reaction of the isoimide with a nucleophile such as an amine or organic hydroxy compound.Photosensitive metal compounds or electroless metal coating catalysts can be coordinated with the compositions obtained.

    摘要： A composition comprises an oxetane oligomer or polymer or copolymer block wherein each repeat group has at least one ether side chain which is terminated by a fluorinated aliphatic group and optionally with the proviso that at least two different repeat units of the oligomer or polymer or copolymer have different Rf groups. The oxetane block is connected to a hydrocarbon polymer block derived from a mono or polyhydroxyl initiator. The terminal fluorinated alkyl groups impart good stain resistance to the oligomer or polymer or copolymer. In another embodiment, a fluorinated aliphatic or alkyl alcohol is reacted with an amino dicarboxylic acid with the reaction product thereof being subsequently grafted to a maleated polyolefin or a maleated polymer derived from a vinyl substituted aromatic monomer. The fluorinated alcohol also imparts good stain resistance to the grafted copolymer. Both compounds can be utilized as an additive in polymers as for example various polyolefins.
