Wu, Zhefu; Yan, Guangming; Lu, Jiehong; Zhang, Gang; Yang, Jie published the artcile< Thermal Plastic and Optical Transparent Polyimide Derived from Isophorone Diamine and Sulfhydryl Compounds>, COA of Formula: C8H3ClO3, the main research area is thermoplastic optically transparent polythioether polyimide.
A series of thermoplastic and optical transparent polyimide-bearing aliphatic rings were manufactured through a two-step approach. The solubility and melt processability were significantly enhanced after embedded with flexible thio-ether moieties. The complex viscosity was within 225.6-3980 Pa·s from 330 to 300 °C. The modified polyimide exhibited moderate mech. strength to 76 MPa. The 5% thermal weight loss temperature was around 443 °C, with a glass transition temperature of 204.6-234.8 °C. Although the cyclic aliphatic segments endowed the obtained PIs with improved optical performance, the transmittance could be up to 82% at 450 nm, while the transmittance of industrialized thermoplastic polyimide derived from PMDA and ODA was less than 20% under the same condition.
Industrial & Engineering Chemistry Research published new progress about Elongation at break. 118-45-6 belongs to class chlorides-buliding-blocks, and the molecular formula is C8H3ClO3, COA of Formula: C8H3ClO3.
