Abstract
The invention concerns a material based on halogenated thermoplastic resin, comprising long fibers, characterized in that at least one long fiber is in close contact with a polymer based on alkyl (meth)acrylate. The invention also concerns the methods for making such a material and its uses.
Claims20
A material consisting essentially of a halogenated thermoplastic polymer, a plurality of fibers and an alkyl-(meth)acryalte-based polymer, wherein the fibers are in intimate contact with the alkyl-(meth)acrylate-based polymer.
A material comprising a halogenated thermoplastic polymer, a plurality of fibers and an alkyl-(meth)acrylate-based polymer, wherein the fibers are in intimate contact with the alkyl-(meth)acrylate-based polymer, and the fibers are substantially parallel to each other.
A process for preparing a material comprising a halogenated thermoplastic polymer, a plurality of fibers and an alkyl-(meth)acrylate-based polymer, wherein the fiber is in intimate contact with the alkyl-(meth)acrylate-based polymer, which comprises:
- impregnating the fiber(s) with the alkyl-(meth)acrylate-based polymer in an emulsion state or in a melt state;
- and
- mixing the impregnated fiber(s) with the halogenated thermoplastic polymer.
A process for preparing a material comprising a halogenated thermoplastic polymer, at least one fiber and an alkyl-(meth)acrylate-based polymer, wherein the fiber is in intimate contact with the alkyl-(meth)acrylate-based polymer, which comprises:
- passing a fiber roving through the alkyl-(meth)acrylate-based polymer in an emulsion state or in a melt state to impregnate the fiber roving;
- sheathing the impregnated fiber roving with the halogenated thermoplastic polymer;
- and
- chopping the impregnated and sheathed fiber roving.
