Abstract/Description
-
Tin-containing ionomers were synthesized by reaction of poly(ethylene/acrylic acid) with mono, di and trihalo-organostannanes using the interfacial condensation technique. The products contain tin ester bonding as evidenced by infrared and mass spectroscopy. They are insoluble but form tough transparent films on application of heat and pressure. The modified ionomer products were flexible with high degrees of substitution and contained both bridging and nonbridging structures with respect to...
Show moreTin-containing ionomers were synthesized by reaction of poly(ethylene/acrylic acid) with mono, di and trihalo-organostannanes using the interfacial condensation technique. The products contain tin ester bonding as evidenced by infrared and mass spectroscopy. They are insoluble but form tough transparent films on application of heat and pressure. The modified ionomer products were flexible with high degrees of substitution and contained both bridging and nonbridging structures with respect to bonding about the tin atom. The analogous products from poly(acrylic acid) were brittle with lower substitutions and contained on nonbridging structure.

Abstract/Description
-
Ethylene/vinyl alcohol (EVOH) copolymers are widely used. These copolymers have been reacted with metallic and organometallic groups for various applications. In the present work, organostannane modified EVOH copolymers are synthesized and characterized and their structure-property relationships, especially with respect to their applications as antibacterials and fungicides as well as their film forming ability, are studied. The modified copolymers exhibit "ionomer-like" thermal properties....

The modified copolymers exhibit "ionomer-like" thermal properties. Some of the properties of the modified EVOH products are also compared to analogous modified polyvinyl alcohol products.
