Latest Patents

Yuting Zhu holds a patent for a self-sensitizing negative polyimide precursor and the method for preparing it. The patent describes a process that begins with 4,4'-dinitro-1,1′-biphenyl-2,2′-dicarboxylic acid as a starting material. This compound undergoes an acylation reaction with thionyl chloride to produce compound 1. Following this, compound 1 is subjected to an esterification reaction with 2-hydroxyethyl methacrylate to yield compound 2. The nitro groups of compound 2 are then reduced to amino groups, leading to the purification of an intermediate of the self-sensitizing negative polyimide precursor. This intermediate is polymerized with 3,3′,4,4′-benzophenone tetracarboxylic dianhydride to create a polyamic acid, which is the self-sensitizing negative polyimide precursor. The unique properties of this precursor allow it to act intrinsically as a photoinitiator when exposed to ultraviolet irradiation, enhancing the exposure sensitivity of the resin.
