Abstract
A method of producing a mineral such as calcium carbonate, glass fibers and layered lattice silicates which is surface modified with an organic material wherein said mineral in substantially dry, particulate form is contacted with an organic monomer, co-monomers or a prepolymer, and surface polymerization or reaction in situ on the mineral is carried out in the presence of gaseous carbon monoxide.
Claims31
A method of producing a mineral selected from the group consisting of metal carbonates, glass fibers and layered lattice silicates which is surface modified with an organic material, wherein the mineral in substantially dry, particulate form is contacted with an organic monomer, co-monomers, or a prepolymer, in the presence of gaseous carbon monoxide.
A method of producing glass fibers which are surface modified with an organic material, wherein the fibers are contacted with an organic monomer, comonomers, or a prepolymer, in the presence of carbon monoxide.
A particulate mineral selected from the group consisting of metal carbonates, glass fibers and layered lattice silicates comprising particles of said mineral, the surfaces of which have been modified by a polymer synthesized in situ in the presence of gaseous carbon monoxide or by reacting a prepolymer in situ on the mineral in the presence of gaseous carbon monoxide.
A composition comprising a filled polymer system comprising a matrix polymer and a filler, said filler comprising particles of a mineral selected from the group consisting of metal carbonates, glass fibers and layered lattice silicates the surfaces of which have been modified by a polymer synthesized in situ on the mineral in the presence of gaseous carbon monoxide.
