Abstract

The present invention relates to the use of at least one monosubstituted succinic anhydride before or during the compounding of a polymer composition comprising at least one polymer as polymer component and at least one calcium carbonate-containing material as filler, in order to reduce the processing period decomposes and / or reduces the melt flow rate of this compounded polymer composition compared to the same polymer composition that has been treated in the same manner in the absence of any mono-substituted succinic anhydride at least 10% and / or increase the viscosity of the compounded polymer composition by at least 10%, wherein the polymer composition does not include polylactic acid.

Description

technical field [0001] The present invention relates to the use of monosubstituted succinic anhydrides in connection with the extrusion of polymer compositions and to a method for reducing polymer decomposition during processing. Background technique [0002] Today, many products are made of plastic because this material has a low density and is thus light, has low thermal conductivity, is strong, is easy to process and is not prone to breakage. Polymers can be produced or obtained from different sources, such as from fossil fuels or from biopolymers, and can be divided into thermoplastic, thermoset and elastomeric materials. The known and most commonly used polymers are e.g. polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polybutylene adipate terephthalate (PBAT), polyhydroxybutyrate ( PHB) and polycaprolactone (PCL). [0003] In addition, particulate fillers are often incorporated into polymeric materials in order to secure polymers and raw materials and...
