Description

[0001]240470 1 Polymer compositionThe use of compositions comprising an epoxy resin as thermoset and glass fibres are widely spread. For example,these compositions are used in wind rotor blades, tubes, construction elements, bikes, cars and ships. However, therecycling of these materials is not easy due to the presence and strong connection of the thermoset and the glassfibres, so that after end of life, these compositions are usually burned or deposited. It is also possible to use these compositions as feedstocks for a gasification and the obtained chemical material can be converted to obtain a polymercomposition. However, this process is very energy consuming and the glass fibres can be hardly recycled via this route.For these reasons, there is a demand for recycling this kind of compositions to obtain a polymer composition or productexhibiting:- increased recycling content of the glass fibres,- increased recycling content of the thermoset,- improved mechanical properties, and- decreased product carbon footprint.This object is at least partially solved by a method comprising the steps:- providing:- one or more thermoplastic(s) TP1, and- a composition C1 comprising:- one or more thermoset(s) TS1,- glass fibres GF1, and- preferably one or more additive(s) A1;- preferably comminuting the composition C1;- mixing and heating a mixture M1 comprising:- the one or more thermoplastic(s) TP1,- the composition C1, and- preferably one or more additive(s) A1,to obtain a polymer composition PC1; and- preferably converting the polymer composition PC1 to obtain a product PRF1.The inventors recognized that surprisingly if the one or more thermoplastic(s) TP1 and the composition C1 are mixed and heated, a polymer composition is obtained exhibiting increased recycling content of the glass fibres, increasedrecycling content of the thermoset, improved mechanical properties, and a decreased product carbon footprint.Further, this object is at least partially solved by a polymer composition PC1 or product PRF1, obtainable by or obtainedby the following method:- providing:- one or more thermoplastic(s) TP1, and- a composition C1 comprising: 240470 2 -one or more thermoset(s) TS1,- glass fibres GF1, and- preferably one or more additive(s) A1;- preferably comminuting the composition C1;- mixing and heating a mixture M1 comprising:- the one or more thermoplastic(s) TP1,- the composition C1, and- preferably one or more additive(s) A1,to obtain a polymer composition PC1; and- preferably converting the polymer composition PC1 to obtain a product PRF1.Further, this object is at least partially solved by a polymer composition PC1 or product PRF1 obtainable by or obtainedby a method described herein.Further, this object is at least partially solved by a polymer composition PC1 or product PRF1, preferably obtainableby or obtained by a method described herein, comprising, preferably consisting of:- one or more thermoplastic(s) TP1,- a composition C1, and- preferably one or more additive(s) A1;wherein the composition C1 comprises, preferably consists of,- one or more thermoset(s) TS1,- glass fibres GF1, and- preferably one or more additive(s) A1.In addition, this object is at least partially solved by a use of a composition C1 comprising:- one or more thermoset(s) TS1,- glass fibres GF1, and- preferably one or more additive(s) A1;as a component and / or as an additive, preferably as a reinforcing agent, in a polymer composition PC1 comprising one or more thermoplastic(s) TP1 and / or in a product PRF1 comprising one or more thermoplastic(s) TP1.
