LIQUID (METH)ACRYLIC SYRUP, METHOD FOR IMPREGNATING A FIBROUS SUBSTRATE WITH SAID SYRUP, AND COMPOSITE MATERIAL PRODUCED AFTER POLYMERISATION OF SAID IMPREGNATION SYRUP

摘要

The invention relates to a viscous liquid (meth)acrylic syrup comprising: a) a (meth)acrylic polymer; b) a (meth)acrylic monomer; and c) an initiator for starting the polymerisation of the (meth)acrylic monomer, said initiator being in the form of a peroxide compound which is a liquid at temperatures of between 0° and 50°C, said syrup being characterised in that the initiator is combined with an accelerator system comprising: d) a reducing compound; e) a metal salt or a mixture of metal salts not comprising cobalt; and f) a tertiary initiator.
