Abstract:
The interfacial polymerization is employed to produce high polymer poly(ester ethers) from the reaction of the salt of dipicolinic acid and various organotin dihalides. They are rapidly synthesized with yield increasing as the length of the organotin alkyl chain increases. Infrared spectroscopy shows the formation of new bands derived from the Sn–O and Sn–O(CO) linkages. IR also shows that the products exist as a combination of molecular geometries about the tin atom. MALDI MS shows formation of ion fragment clusters to five and six units in length. The products show good inhibition of a variety of cancer cell lines including two pancreatic cancer cell lines.
