THERMALLY-REVERSIBLE CROSSLINKING OF POLYMERS

摘要

The present invention is a rheology-modifiable polymeric composition or a fr ee- radical crosslinkable polymeric composition, wherein the resulting rheology~modifying bond or crosslinking bond is a thermally-reversible bond. The resulting polymer is prepared from at least one polymer which upon formi ng free radicals preferentially degrades or carbon-carbon crosslinks. The prese nt invention permits suppression of the preferential reaction while permitting the polymer to be coupled or crosslinked through a thermally-reversible bond . Suppressing the undesirable degradation or carbon-carbon crosslinking reacti on and permitting the desirable reaction yield a rheology-modified polymer or a free-radical thermally-reversibly crosslinked polymer.
