Abstract
The present invention relates to a liquid (meth)acrylic syrup, its method of polymerization and article obtained thereof. In particular the present invention deals with a liquid (meth)acrylic syrup comprising an initiation system for polymerization at low temperature. More particularly the present invention relates to a liquid (meth)acrylic syrup comprising an initiator system for polymerization at low temperature, said initiating system comprises at least one accelerator, at least one organic aldehyde, at least one peracid and at least one liquid peroxy compound; an impregnation process for a fibrous substrate, the liquid (meth)acrylic syrup for implementing this process, and the obtained impregnated fibrous substrate. The impregnated fibrous substrate is suitable for manufacturing mechanical or structured parts or articles. The present invention concerns also the process for polymerizing a liquid (meth)acrylic syrup comprising an initiation system for polymerization at low temperature said initiating system comprises at least one accelerator, at least one organic aldehyde, at least one peracid, and at least one liquid peroxy compound. The present invention concerns also manufactu…
