There is limited evidence in experimental animals for the carcinogenicity of bis(2-chloro -1 -methy lethyl)ether. 

A further example of the use of 2//-thiopyrans as surrogates for m-substituted dienes involves the use of the protected 3,4-dihydio-3-(3-oxobutyl)A//-thiopyranA-onc, 3-[2-(2-methyl-l,3-dioxolan-2-yl)ethyl]-4-[tris(l-methy-lethyl)silyl)oxy-2//-thiopyran 328 as an equivalent of l-ethenyl-2-methylcyclohexene in Diels-Alder reactions. The thiopyran reacted with various maleimides to yield the endo cycloadducts and with methyl propenoate to give the exo adduct under either thermal or Lewis-acid-catalyzed conditions. In the latter case concomitant release of the protected ketone functions occurs, acid-catalyzed cyclization of which generates a fused cyclohexenone ring (Scheme 67). Desulfurization, preferably before the aldol cyclization, leads to derivatives of 2,3,4,4a,5,6,7,8-octahy-dro-4a-methylnaphthalenes < 1997CJC681 >.

The presence of liquids or vapors in the enviromnent of a polymeric component affects the response to external mechanical forces. Thus, for instance polyarylate (Par) under uniaxial extension exhibits exclusively shear yielding without crazing. However, exposure to organic vapor (methy-lethyl ketone) results in crystallization, embrittlement, and conversion of the response to deformation from shear yielding to crazing [42].
