TL;DR: A variety of porous organic polymers, metal-organic frameworks, conjugated microporous polymers and polymers of intrinsic microporosity have been designed and synthesized using simple and efficient procedures as mentioned in this paper.

TL;DR: Three new tetra-Schiff bases were synthesized and characterized to be used as photostabilizers for poly(vinyl chloride) (PVC) films, with Schiff base 1 being the most effective additive upon irradiation, followed by 2 and 3.

TL;DR: Three organotin(IV) complexes containing ciprofloxacin as a ligand were used as additives to inhibit the photodegradation of polyvinyl chloride films upon irradiation with ultraviolet light and the results obtained indicated thatorganotin( IV) complexes stabilized poly(vinylchlor chloride) and the dimethyltin(IV), the most efficient additive.

TL;DR: Results reflect that these compounds effectively inhibit the photodegradation of PVC, possibly by acting as hydrogen chloride and radical scavengers, peroxide decomposers, and primary photostabilizers.

TL;DR: Various mechanisms, including direct absorption of ultraviolet irradiation, radical or hydrogen chloride scavenging, and polymer chain coordination, could explain how the diorganotin(IV) complexes stabilize PVC against photodegradation.
