Abstract
A method for the isolation of oligomeric 2, 2-difurylpropane (DTHFP) suitable for use on an industrial scale. A method can include using oligomeric 2, 2-difurylpropane, in particular, its use can be as a polar modifier for butadiene and styrene butadiene polymerization so is to produce rubber. Utilizing the material as an alternative to DTHFP in rubber production avoids subsequent leaching of the DTHFP into the environment as the oligomeric 2, 2-difurylpropane (DTHFP) gives rise to much lower levels of leaching.
