Tap-mediated, rheology-modified polymers and preparation methods

A triallyl phosphate-mediated, rheology-modified polymer prepared from a reaction mixture comprising:

• (a) a first quantity of a first free-radical, chain-scissionable organic polymer, wherein the polymer is pendantly-grafted with triallyl phosphate, and
• (b) a second quantity of said first free-radical, chain-scissionable organic polymer or a quantity of a second free-radical chain-scissionable organic polymer,
• wherein the triallyl phosphate-mediated, rheology-modified polymer has a Relaxation Spectra Index (RSI) greater than that of the first free-radical, chain-scissionable organic polymer.

A process for preparing a triallyl phosphate-mediated, rheology-modified polymer comprising the step of reacting:

• (a) a free-radical, chain-scissionable organic polymer, and
• (b) triallyl phosphate,
• wherein the triallyl phosphate-mediated, rheology-modified polymer has a Relaxation Spectra Index (RSI) greater than that of the free-radical, chain-scissionable organic polymer.
