- Abstract
- The effects on the smoke density and products of combustion for a wide variety of different factors were investigated. Since the smoke level is a function of the amount of resin burned, values of the specific optical density and products of combustion are reported per gram of resin consumed. This smoke density is affected by both the unsaturated polyester backbone and the reactive diluent portions of the resin. Resins based on phthalic anhydride and propylene glycol produced the most smoke, while those based on isophthalic acid and neopentyl glycol produced the least. In general, increasing the styrene loading level produced more smoke although there appears to be at least one notable exception.
