Abstract:
Disclosed herein is a copolymer solution, comprising: a first polymer chain, comprising one or more capped ends formed by reacting a polyester diol with an anhydride; a second polymer chain, comprising two or more repeating units of the first polymer chain propagated from the one or more capped ends; and a third polymer chain, comprising one or more repeating units of the first polymer chain having at least one branched chain propagating from the one or more capped ends; wherein the copolymer solution has a viscosity of from 50 cP to 1000 cP at room temperature; and wherein each of the first polymer chain, the second polymer chain, and the third polymer chain is independently capable of crosslinking with the first polymer chain, the second polymer chain, the third polymer chain, or a combination thereof. Also disclosed herein are methods of making the same.

Abstract:
A film comprising a copolyester wherein said copolyester comprises repeating units derived from an aliphatic glycol, an aromatic dicarboxylic acid, and a comonomer (M) selected from the group consisting of N,N '-bis-(2-hydroxyalkyl)-bicyclo-[2,2,2]-oct-7- ene-2,3,5,6-tetracarboxylic diimide(BODI)and 2-hydroxyalkyl-2-[p-(2- hydroxyethoxycarbonyl)phenyl]-1,3-dioxo-2H-isoindole-5-carboxylate (DOIC), wherein the number of carbon atoms is the 2-hydroxyalkyl group is 2, 3 or 4, and wherein comonomer (M) constitutes a proportion of the glycol fraction of the copolyester.
Abstract:
A polyester film comprising a copolyester which comprises repeating units derived from an aliphatic glycol, an aromatic dicarboxylic acid, and the monomer of formula (I): wherein n = 2, 3 or 4, and wherein comonomer (I) constitutes a proportion of the glycol fraction of the copolyester.
Abstract:
The present invention addresses the problem of providing: a polyimide which has excellent transparency, high heat resistance and low linear thermal expansion coefficient at the same time, while exhibiting solvent workability (excellent solubility and film formation performance) by means of a low moisture-absorbing solvent; and a method for producing this polyimide. In order to solve the above-mentioned problem, the present invention provides a polyimide that contains a constituent unit represented by formula (1). (In the formula, each R independently represents a hydrogen atom or an alkyl group having 1-6 carbon atoms, provided that at least one of two R groups bonded to a same benzene ring is an alkyl group.)
