摘要： QM 35803 CATALYSTS An extrusion polymerisation process is described in which the polymerisation of vinylic monomers, in particular acrylic monomers, is carried out in bulk in an extruder. The polymerisation reaction is catalysed by a catalyst composition comprising an initiator, e.g. a ureido substituted silane, and a co-catalyst which is a salt providing a source of anions, e.g. fluoride ions.
