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 refers to a formulation suitable for the manufacture of a pressure sensitive adhesive, said formulation comprising: a) 40-95 wt % of polyalkylene carbonate having a number average molecular weight higher than 17.000 Da; b) 5-60 wt % of a polyether carbonate polyol having CO2 groups randomly incorporated in the chemical structure thereof, wherein the content of CO2 ranges from 0.5 to 40 wt %, based on the total weight of the polyether carbonate polyol; and c) optionally, less than 30 wt % of a tackifying resin, provided that said formulation does not contain any reticulating agent.

Abstract: The present invention refers to a composition comprising: (a) 5-95 wt % of a poly(alkylene carbonate), wherein said poly(alkylene carbonate) has a glass transition temperature equal to or lower than 30° C. and a number average molecular weight higher than 15,000 Da; and (b) 95-5 wt % of poly(alkylene carbonate), wherein said poly(alkylene carbonate) has a glass transition temperature higher than 30° C. It also refers to a method for producing said composition as well as to its use for preparing adhesive formulations with improved thermal stability and adhesion properties.
