Alkynes undergo many of the same reactions as alkenes, but can react twice because of the presence of the two p -bonds in the triple bond. Herein we propose the preparation of crosslinked polymers from off-stoichiometric oxa-Michael formulations proceeding via a self-limiting base catalyzed reaction between difunctional Michael acceptors and substoichiometric amounts of diols followed by anionic polymerization of the remaining vinyl groups. This hydrogen can be removed with a very strong base such as the amide ion. A common example of a pair of enantiomers is your hands.
