  • Publication number: 20200010639
    Abstract: The present invention relates to a liquid composition comprising a monomer, a (meth)acrylic polymer and at least two initiators. In particular the present invention relates to a liquid composition comprising a monomer, a (meth)acrylic polymer and at least two initiators that have a different half life time. That liquid composition can be used as a syrup and especially as a syrup for impregnation of fibres or fibrous material. Also concerned is a thermoplastic material obtained after polymerization of the liquid composition. The invention also relates to a process for manufacturing such a liquid composition. The invention also relates to a process for impregnating a fibrous substrate of long fibres with said liquid composition. The invention also relates to a fibrous substrate impregnated with said liquid composition which is useful for manufacturing composite parts.

  • Publication number: 20190233603
    Abstract: The present invention relates to a liquid composition comprising a monomer, a (meth)acrylic polymer and a multistage polymer. In particular the present invention it relates to a liquid composition comprising a monomer, a (meth)acrylic polymer and a multistage polymer that can be used as a syrup and especially as a syrup for impregnation and for the preparation of for reinforcing the impact strength of a thermoplastic material obtained after polymerization of the syrup. The invention also relates to a process for manufacturing such a syrup. The invention also relates to a process for impregnating a fibrous substrate of long fibers with said viscous liquid syrup. The invention also relates to a fibrous substrate preimpregnated with said syrup which is useful for manufacturing composite parts. More particularly the present invention relates also to a process for preparing a liquid composition comprising a (meth)acrylic monomer, a (meth)acrylic polymer and a multistage polymer.

  • Publication number: 20190225729
    Abstract: The present invention relates to a liquid composition comprising a monomer, a (meth)acrylic polymer and at least one flame-retardant substance (FD1) chosen from a phosphorus-based additive. In particular the present invention it relates to a liquid composition comprising a monomer, a (meth)acrylic polymer and at least one flame-retardant substance (FD1) chosen from a phosphorus-based additive that can be used as a syrup and especially as a syrup for impregnation and for the preparation for improving the fire resistance of a thermoplastic polymer or matrix obtained after polymerization of the syrup. Also concerned is a thermoplastic material obtained after polymerization of the liquid composition or syrup. The invention also relates to a process for manufacturing such a liquid composition or syrup. The invention also relates to a process for impregnating a fibrous substrate of long fibers with said liquid composition or syrup.
