ABSTRACT:
A polymer having pendant silyl 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 silyl ether groups and by the selection of said silyl ether groups. The polymer can be formed by reacting a olefin monomer with a silyl monomer or by grafting a silyl monomer onto an unsaturated polyolefin. Preferably, the silyl monomer is either a vinyl trimethylsilyl ether monomer, a vinyl dimethylchlorosilane monomer, or a vinyl methyldichlorosilane monomer. Preferably, the olefin monomer is decene, and the unsaturated polyolefin is polydecene.
