20110098823 | TIBIAL COMPONENT WITH FLEXIBLE RIM - A tibial prosthesis including an articulating component and a tray component with a rim that extends proximally to support the articulating component, the tray component enabling flexion of the rim relative to a bone-contacting surface of the tray component. | 04-28-2011 |
20110098824 | TIBIAL COMPONENT WITH ENHANCED RADIAL CEMENT FIXATION - A cemented tibial prosthesis having a bone-contacting surface with a porous outer rim. With the bone-contacting surface seated against a resected proximal tibia, bone cement or another suitable adhesive will travel into the pores of the porous outer rim to enhance the connection between the tibial prosthesis and the tibia. | 04-28-2011 |
20120264851 | ARGILLACEOUS GYPSUM - Additives selected from primary, secondary, and tertiary alkyl amines and quaternary alkyl ammonium compounds are added to argillaceous gypsum compositions comprising comb polymers to improve the workability thereof. Argillaceous gypsum compositions, dispersing agents, a method for producing argillaceous gypsum compositions, and molded parts that can be produced from the gypsum compositions are also described. | 10-18-2012 |

20130217808 | PRODUCTION OF COMB POLYMERS BY MEANS OF ESTERIFICATION - The invention relates to a method for producing comb polymers, wherein at least one polycarboxylic acid or a salt thereof is esterified with at least one monohydroxy polyether, comprising the following steps: (a) preparing a reaction mixture containing at least one polycarboxylic acid; (b) heating the reaction mixture to at least 80° C.; (c) adding a base; and (d) esterifying the mixture at a reaction temperature of at least 80° C. obtaining a comb polymer, wherein at least one monohydroxy polyether is added to the reaction mixture in step (a) and/or (b). The invention further relates to comb polymers, cement compositions, molded bodies, and uses of comb polymers. | 08-22-2013 |
20140163161 | COMB POLYMERS WITH DELAYED ALKALINE HYDROLYSIS - Comb polymers having carboxyl/carboxylate and ester groups, containing a) 0.1-0.9 mol fractions of a partial structural unit S1, which is derived from an acrylic/methacrylic or maleic acid unit, b) 0-0.4 mol fractions of a partial structural unit S2, which is derived, for example, from an acrylic/methacrylic or maleic acid unit, which is esterified by means of a C | 06-12-2014 |
20140249254 | DISPERSING AGENT FOR SOLID SUSPENSIONS - A polymer having the formula (XIV) | 09-04-2014 |
20150232597 | PLASTICIZER HAVING CATIONIC SIDE CHAINS WITHOUT POLYETHER SIDE CHAINS - The invention relates to the use of at least one comb polymer which includes side chains which have at least one cationic group, and does not include side chains having polyether groups, and which has a main chain which has carboxyl groups, as dispersant for hydraulically settable compositions. The invention also relates to hydraulically settable cement compositions, mouldings, comb polymers and method for producing comb polymers. | 08-20-2015 |
