Assignee: ARKEMA FRANCE
Field: Macromolecular chemistry, polymers (Chemistry)
Classification: CPC C | IPC C

Claim 0:
1. A (meth)acrylic composition comprising:
(a) 100 parts by weight of a liquid (meth)acrylic syrup comprising:
(a1) from 10% by weight to 50% by weight of one or more (meth)acrylic polymers P1, and
(a2) from 50% by weight to 90% by weight of one or more (meth)acrylic monomers M1, each monomer M1 comprising only one (meth)acrylic function per monomer,

(b) from 20 parts by weight to 300 parts by weight of a mineral filler C,
(c) from 0.01 part by weight to 5 parts by weight of a (meth)acrylic monomer M2, the monomer M2 comprising at least two (meth)acrylic functions per monomer,
(d) from 0.01 part by weight to 10 parts by weight of a (meth)acrylic monomer M3, the monomer M3 being:
either a (meth)acrylic monomer M31 comprising only one (meth)acrylic function per monomer, the monomer M31 being different from the monomer(s) M1,
or a (meth)acrylic monomer M32 comprising at least two (meth)acrylic functions per monomer, the monomer M32 being different from the monomer M2,

(e) from 0.01 part by weight to 5 parts by weight of a polymerization initiator, and
(f) optionally, a coupling agent.
