ABSTRACT:
A homogeneous composite polymer containing, in an interpenetrated form, 20% to 80% by weight of silica and 80% to 20% by weight of a three-dimensional crosslinked acrylic, vinyl and/or allyl copolymer comprising, in a copolymerized form, 98% to 70% by weight of at least one monofunctional acrylic, vinyl or allyl monomer and 2 % to 30% by weight of a difunctional acrylic or allyl crosslinking monomer is useful in liquid chromatography.
