DOCUMENT TYPE: Journal CA Section: 35 (Chemistry of Synthetic High Polymers) The effect of the chem. structure on the reactivity of alkenes used in thiol-ene photopolymns. was studied with real-time IR spectroscopy. Model studies of thiol-ene photoreactions with various monofunctional hydrocarbon alkenes and the monofunctional thiol ethyl-3-mercaptopropionate were performed to identify and understand structure-reactivity relationships. The results demonstrate that terminal enes react rapidly with thiol, achieve complete conversion, and are independent of the aliph. hydrocarbon substituent length. Disubstitution on a single carbon of a terminal ene significantly reduces the reactivity, whereas substitution on the carbon a to the terminal ene has a minimal influence on the reactivity. Internal trans enes display reduced reactivity and a lower overall conversion and deviate from the std. thiol-ene reaction mechanism because of steric strain induced by 1,3-interactions. The reactivity and conversion of internal trans enes decrease as the substituents on the ene become larger, reaching a min. when the substituent size is greater than or equal to that of Pr groups. Internal cis enes react rapidly with thiol; however, they undergo a fast isomerization-elimination reaction sequence generating the trans ene, which proceeds to react at a reduced rate with thiol. The reactivity of cyclic enes is dictated by ring strain, stereoelectronic effects, and hydrogen abstractability. The reactivity trends in the model studies were used to explain the photopolymn. mechanism and kinetics of a series of multifunctional thiol-ene systems. .
