PAPER COATING COMPOSITIONS COMPRISING A POLYMER DISPERSION FROM ROOM TEMPERATURE LIQUID AND GASEOUS MONOMERS |
摘要 |
<p>Paper coating compositions comprise inorganic pigments and an aqueous polymeric dispersion comprising dispersed polymeric particles. The polymers are obtainable by polymerization of a first monomer that is liquid at room temperature, has a boiling point of at least 50° C. and a glass transition temperature of at least 20° C. as homopolymer, and a second monomer that is gaseous at room temperature, has a boiling point of below 0° C. and a glass transition temperature of below−30° C. as homopolymer. The dispersed polymeric particles have an average size of below 150 nm and a glass transition temperature in the range from−10 to +30° C.</p> |
