  • Alkyl hydroxyalkyl cellulose ethers, methods of making, and use in cements and mortars
    Patent number: 10370459
    Abstract: Disclosed are methods for the preparation of alkyl hydroxyalkyl cellulose ethers, and the use of such alkyl hydroxyalkyl cellulose ethers in the preparation and use of mortars and other cement-based systems; also disclosed is a hydraulic composition containing at least one retarder, at least one accelerator and a cellulose ether having a prolonged open time without deterioration of the other cement tile adhesive properties such as workability, setting time, strength development and sag resistance; and further disclosed are dry mortars containing encapsulated calcium chloride used in preparing mortar materials for use in construction, and the preparation and use of such mortars in cold weather environments is also disclosed.

  • Coating compositions containing lactam-functionalized polymer
    Patent number: 10358574
    Abstract: An aqueous coating composition comprising at least 0.5 wt % of a lactam-functionalized polymer is disclosed. The lactam-functionalized polymer includes lactam-functionalized polyacetal polyether, polyhemiaminal polyether or polyaminal polyether. The aqueous coating composition can increase an open time of a water-borne latex paint. A method of increasing an open time for an aqueous coating composition of a water-borne latex paint using the lactam-functionalized polymer is also disclosed.
