| Abstract |
The composition of volatile products of cycloaliphatic epoxy resins UP-640 and UP-650 T, polyoxypropylene epoxides DE-1000, DE-2000, TE-750, TE-1500 and epoxy-diane ED-6 was determined. The cycloaliphatic epoxy resins and polyoxypropylene epoxides (POPE) differ from earlier epoxy resins in both component composition and content. Such highly toxic components as allyl chloride and styrene can volatilise along with epichlorohydrin and toluene from UP-640 and UP-650 T, in contrast to epoxy resins. Volatile products of POPE include acetone, allyl chloride, ethanol and dioxane equally with the usual components of diane resins. The main component taken into account for standardisation cannot be only epichlorohydrin. In the case of hygienic standardisation of POPE, in particular, acetone is chosen as the volatile component because of its proportion, boiling point and volatilising proportion in comparison with other volatile products. |
