Abstract: A mixture having a poly(alkylene carbonate) and a non-polymeric organic molecule having a molecular weight below 1,000 Da may be used as a self-healing material. The non-polymeric organic molecules having a molecular weight below 1,000 Da may also be used to impart self-healing behaviour to a mixture having a poly(alkylene carbonate).

Abstract: The present invention relates to the use of ultra-high-molecular-weight polyolefin particles as proppants for treating subterranean formations, as well as to compositions comprising said particles and to fracturing methods employing said particles.
