Abstract (en)
[origin: WO2018074967A1] The present invention refers to a method for increasing the melt flow rate in a polycaprolactone thermoplastic composition, said method comprising the step of adding 0.5- 20.0 % by weight of calcium carbonate to said polycaprolactone thermoplastic composition. The present invention also refers to an article comprising a thermoplastic composition prepared according to said method and to the use of said article for manufacturing of items such as plastic bags and films as well as items produced by casting and molding techniques.
