Solvents for use in the layer coating liquid are not particularly limited if capable of solving the above-mentioned resin. Specific examples thereof typically include aromatic hydrocarbons such as toluene and xylene; ketones such as acetone and methyl ethyl ketone; and ethers such as tetrahydrofuran ...
Suitable solvents for use in the thermosetting resin liquid include ketone such as methyl ethyl ketone, acetone, methyl isobutyl ketone, and cyclohexanone; ethers such as dioxane, tetrahydrofuran, and ethyl cellosolve; aromatic solvents such as toluene, and xylene; halogen-containing solvents such as ...
;SOLUTION: A solution which has at least one kind of polymer chosen from the group consists of polyamide, polyimide, polyester, polyetherketone, polyamideimide and polyetherimide dissolved in a solvent is coated on a base material. This birefringence film is formed after drying by using a base ...
5) group 基 6) side carboxyl 羧基侧基 1. Poly(aryl ether sulfone ether ketone ketone) withside carboxyl(PESEKK-A) attached to the main chain was synthesized by Friedel-Crafts polycondensation of 4,4′-diphenyoxyl diphenyl sulfone(DPODPS) with trimellitic anhydride chloride(TMAC). ...
having a substituent constant &sgr;p of 0 or more by a Hammett low; and A and B are the same or different from each other, each representing an organic group having at least one selected from a halogen atom, cyano group, nitro group, sulfonyl group, ester structure and ketone structure...
The basic reaction of positive photoresist involves the conversion of the dissolution inhibitor (diazoketone) to a dissolution enhancer (carboxylic acid). The novolac-type resin is basically unchanged, but its solubility is controlled by... ML Long,J Newman - 《Proceedings of Spie the International...
Patterns of odour similarity among carbonyls and their mixtures The odours of five carbonyls: heptanone, octanone, octenal, nonenal and decadienal, and two mixtures of each ketone with each aldehyde, giving 17 sample types in all, were compared using two non-quantitative, non-descriptive procedures...
A sequential, organocatalysed asymmetric reaction to access chiral 1,2-oxazines from achiral ketone starting materials is reported, which proceeds in moder... Sirirat,Kumarn,M David,... - 《Chemical Communications》 被引量: 122发表: 2006年 ...
Positive and negative photostructures are formed after the polyimide (PI) of 4,4′-biphthalic anhydride (BPA) and 4,4′-diamino-3,3′-dimethyldiphenylmethane (DADMDPM), PI(BPA/DADMDPM) is doped with Michler′s ketone (MK) and benzophenone (BP), respectively, and is subjected to UV ...
