Claim:
A method for manufacturing a sheet of paper from pulp, comprising obtaining said pulp from a mixture of: natural fibers, synthetic fibers or a combination thereof, water, and at least one aqueous suspension and/or aqueous dispersion of at least one mineral material, wherein said at least one of said aqueous suspension and/or dispersion comprises, as a steric dispersing agent of said at least one mineral material, at least one copolymer having: a) at least one vinyl monomer; and b) at least one non-ionic monomer, of formula (I): where: m and p represent a number of alkylene oxide units less than or equal to 150, n represents a number of ethylene oxide units less than or equal to 150, q represents an integer at least equal to 1 wherein 5≦(m+n+p)q≦150, R 1 represents hydrogen or the methyl or ethyl radical, R 2 represents hydrogen or the methyl or ethyl radical, R represents a radical having an unsaturated polymerizable function, R′ represents hydrogen or a hydrocarbonated radical having 1 to 40 carbon atoms, or a mixture of several monomers having formula (I).
