ABSTRACT:
A polymer having pendant vinyl ether groups is disclosed having a minimum solubility parameter of 6.85 (cal/cc).sup.1/2 or less. That minimum solubility parameter is reduced to 6.85 (cal/cc).sup.1/2 or less by control of the number of pendant vinyl ether groups and by the selection of said vinyl ether groups. Preferably, the polymer has a molecular weight of over 1000 and is formed by reacting an olefin monomer (such as decene) with a vinyl(ethyl ether) monomer or by grafting a vinyl ether monomer onto an unsaturated polyolefin (such as polydecene).
