"We were able to detect these acetals
bothin 'Creme Brulee' e-liquid as well as in the generated from it," Hanno Erythropel, lead study author and an associate research scientist at the university, said in a (https://news.yale.edu/2019/07/30/juul-users-inhaling-chemicals-not-listed) press release .A
An experiment in which polychloroprene and a cyclic acetal
, both dissolved carbon tetrachloride, were exposed to ozone showed that the double bonds of the elastomer were not attacked before approximately 90% of the double bonds of the antiozonant had reacted (figure 1) (ref.
The objective of this study was to determine the feasibility of transforming poly(vinyl acetate) to poly(vinyl acetals
) in solvent-free conditions and also during use of supercritical C[O.sub.2] as a processing aid.
Aardalloy 3326 is a high-viscosity homopolymer acetal
alloyed with higher levels of elastomers and modifiers than 3300.

Delrin 500MP acetal
is offered as an economical material choice for parts requiring low wear, friction, and squeak.
copolymers include general-purpose, impact-modified, and antimicrobial grades.
Other new Delrin acetal
resins make possible the injection molding of flat shapes and large parts without the warp problems associated with standard acetals
performance in automotive fuels was recently illustrated in a series of 5000-hr comparison tests.
