Beschreibung
Zusammenfassung:	Disclosed herein is a method of making a rigid polymer product, such as an impact resistant halogen containing polymer, comprising adding to a halogen containing resin at least one mineral filler comprising coated calcium carbonate having a hydrophobic coating derived from at least one aliphatic carboxylic acid comprising at least 10 carbon atoms in the main chain, and no more than 0.01% by weight of agglomerates or particles having a particle size greater than 44 mum. Further disclosed herein are rigid polymer products comprising this coated calcium carbonate for use in applications that benefit from impact resistant properties, such as vinyl siding and PVC pipes and fittings.
