Thionolactones as Additives for Vinyl Network Degradation

The introduction of low levels of cleavable comonomer additives into existing vinyl polymerization processes may facilitate the production of chemically deconstructable and recyclable variants with otherwise equivalent properties. The present disclosure describes cleavable comonomer approach as a viable strategy toward circular vinyl polymers. The present disclosure describes copolymers comprising ml instances of the first repeating unit of Formula (i); m2 instances of the second repeating unit of Formula (iiA) or (ii-B); and optionally one or more types of additional repeating units. The disclosure also provides compounds of the formula:, or a tautomer or salt thereof. The present disclosure further describes methods of preparation, compositions, and kits.
