While it is known that the Rolie Poly model is not guaranteed to be thermodynamically consistent, definite examples of a thermodynamically inconsistent prediction have not yet been published. Additionally,
the source of the problem (and its historical context) may not be widely known. This talk covers useful background information and provides a definite example of negative entropy production in an experimentally
relevant flow. We also discuss the implication of negative entropy production in terms of an experimentally measurable quantity (recoverable strain).
