Latest Patents

Johann Plank holds a patent for a copolymer that serves as a dispersant for cement and cement compositions. This copolymer demonstrates sufficient dispersibility for various types of cements, including those with low fluidity, which are often challenging to work with. The copolymer is synthesized by polymerizing monomer components that include an unsaturated (poly)alkylene glycol ether monomer, an unsaturated carboxylic acid monomer, and an unsaturated cross-linkable monomer. The cross-linkable monomer can be either allyl itaconate or allyl citraconate, or an ester derived from these compounds. Additionally, it can also be an ester formed from the reaction of specific acids with a (poly)alkylene glycol or a (poly)alkylene glycol ether.
