Cyclized Copolymer of Methacrylic Anhydride and an Application to Photoresist with Photo-Acid Generator
نویسندگان
چکیده
The cyclized copolymerization of methacrylic anhydride with N phenyldimethacrylamide and methacrylonitrile was carried out. The polymer consists of six-membered cyclic acid anhydride and five-membered imide ring. The cyclic acid anhydride was hydrolyzed by generated acid catalyst from photo-acid generator (PAG). The hydrolyzed copolymer is dissolved in an alkaline solution. We applied this copolymer with PAG to photoresist based on the chemical amplified system and obtained good patterns of positivetone image.

A magnetic nano-composite based on modified styren-maleic anhydride copolymer and Fe3O4 nano-particles was introduced as a new sorbent for solid-phase extraction and preconcentration of trace levels of silver ion from aqueous solutions. The size and morphology of the nano-sorbent were characterized via X-ray diffraction analysis, scanning electron microscopy and Fourier transform infrared spect...
متن کاملFabrication and Characterization of Proton Conductive Membranes Based on Poly(methyl methacrylate-co-maleic anhydride)
In this study, proton conductive composite membranes were produced by using a poly(methylmethacrylate-co-maleic anhydride) (P(MMA-co-MAH)) copolymer and phosphotungstic Acid (PWA) as an additive of the proton conductive agent. P(MMA/MAH) 70/30, 50/50, and 30/70 were synthesized using a free radical polymerization reaction. PWA with a concentration of 2% was added to...

Chitin-methacrylate (CM) was prepared by the reaction of methacrylic acid on chitin in 5% LiCl/DMAc in the presence of N,N'-dicyclocarbodiimide and dimethylaminopyridine. The resultant chitin-methacrylate product was isolated in 61% yield and was found to be readily water-soluble. The derivative was found to be a mixture of methacrylate and methacrylic-dimethylaminopyridine complex substituents...
