摘要： A chalking-resistant titanium dioxide pigment is produced by mixing the pigment with a vinyl polymer, in form of an aqueous latex, applying the polymer to the pigment in quantities of about 0.1 to 30% by weight based on the final pigment and the mixture containing at least about 30% of water by weight. The polymer is then coagulated, the aqueous phase separated and the pigment-plus-polymer dried. Due to some apparent complexing, the polymer cannot be quantitatively dissolved away from the pigment. The pigment produces chalking-resistant lacquers, paints and coating compositions.

摘要： Degradable polymers are obtained by either mixing a conventional thermoplastic polymer and a transition metal containing polymeric product in which the transition metal is bound in complex form through 1,3-dicarbonyl groups attached to the polymeric product or using the polymeric product as polymer alone. These polymers are degradable under the effect of natural weathering, ultraviolet rays and/or sunlight.
