Exo-N-pentafluorophenylbicyclo[2.2.1]hept-5-ene-2,3-dicarboximide(I) readily undergoes metathesis ring-opening polymerization when exposed to conventional metathesiscatalysts such as WCl6/ME4Sn and MoCl5/Me4Sn; by contrast, its endo isomer (II) is not homopolymerized but can be copolymerized with (I). The microstructures of the resulting polymers are established and discussed.
当暴露于常规复分解催化剂(例如WCl 6 / ME 4 Sn和MoCl 5 / Me )中,Exo-N-五氟苯基双环[2.2.1]庚-5-烯-2,3-二甲酰亚胺(I)容易发生复分解开环聚合4锡; 相反,其内异构体(II)不是均聚的,而是可以与(I)共聚的。建立并讨论了所得聚合物的微观结构。

The present disclosure provides copolymers prepared by polymerizing a first monomer comprising at least one C=C and/or at least one C=C; and a second monomer of Formula (B): wherein at least one first monomer and/or at least one second monomer comprises a latent-fluoride moiety (e.g., pentafluorophenyl). Upon contacting the copolymers with a nucleophile (e.g., a thiol) and/or a base, the latent-fluoride moiety may release fluoride ions, which may in turn degrade the copolymers by cleaving the O-Si bonds. The copolymers may be useful for drug delivery, or as degradable (e.g., biodegradable) polymers, adhesives, coatings, or structural materials.
