Description and Uses
Divinylbenzene exists as o-, m-, and p-isomers. The commercial product contains all 3 isomers, but m-isomer predominates. Usually contains an inhibitor to preventpolymerization. The CAS number for the mixed isomersappears on most regulatory lists.DVB is a pale, straw-colored liquid. Molecularweight= 130.20; Specific gravity (H2O:1) 5 0.93; Boilingpoint= 195-200℃; Freezing/Melting point = 2 66.7to 252℃; Vapor pressure= 0.7 mmHg at 20℃; Flashpoint= 62℃ (cc); 76℃ (oc); Autoignition temperature=469℃. Explosive limits: LEL = 0.7%; UEL= 6.2%.Hazard Identification (based on NFPA-704 M RatingSystem): Health 1, Flammability 2, Reactivity 2. Insolublein water.
Comonomer for preparation of crosslinked polymers in production of ion exchange beads and gel permeation chromatography polystyrene beads; polymerization monomer for synthetic rubber, drying oils, and casting resins
