摘要：
The invention resides in the use, as an agent reducing the viscosity of a thermoplastic or thermosetting paste filled with a calcium carbonate, of a calcium carbonate characterised in that it is obtained by dry-grinding, firstly, and in that it is dry-ground in the presence of a grinding aid agent which is a copolymer of (meth)acrylic acid with a monomer containing an alcoxy or hydroxy polyalkyleneglycol group, secondly. The invention also concerns the filled thermoplastic and thermosetting pastes obtained in this manner.
