Sniffing alkyl nitrites can cause skin irritation, dizziness, low blood pressure, headaches and other unpleasant side effects.

In this study, the researchers synthesized PSPBs with different molecular weights and added varying amounts of hydrophobic monomers individually and with different alkyl chains through a process known as reversible addition-fragmentation chain transfer polymerization.

The method involves combining three chemicals: an amine "head," two alkyl epoxide "tails" and, finally, two acyl chloride "branched tails."

The attachment of the alkene produces a transient reactive species, which then reacts with the alkyl halide to form the new C–C bond.

The 71-year-old singer said Mr. Rivera and his then-producer pushed her into a bathroom, forced her to inhale the recreational drug alkyl nitrite and then “proceeded to grope” her.
