摘要： Conventional cement admixtures used in order to enhance the flowability of a cement composition or prevent slump loss are problematic in that their performances are unsatisfactory or they cause heterogeneity of a cement composition. To solve these problems, the invention provides a cement admixture comprising a cross-linked polymer wherein a linkage having a structural unit comprising at least one divalent group represented by formula (I) is formed between the main chains each having a structure of a water-soluble polymer with a molecular weight of 500 to 100,000 (I), wherein R?1 and R2¿ represent each independently (a) or (b) provided that R1 may be absent when R2 represents (c); and R and R1 represent each independently an alkyl group having 1 to 5 carbon atoms.

摘要： An improved process for making allylic/ethylenic copolymers is disclosed. Increasing the reaction temperature during addition of the ethylenic monomer/initiator mixture results in a substantial increase in the polymer yield obtained compared with the yield from a conventional process in which a constant temperature is used. Copolymers made by the process include valuable coating resins such as styrene-allyl alcohol and hydroxy-functional acrylic copolymers.

摘要： Allylic copolymer resins and processes for making them are disclosed. The resins are made by copolymerizing an ethylenic monomer, a monofunctional allyl monomer, and a multifunctional allyl monomer under free-radical conditions. The multifunctional allyl monomer is used in an amount and manner effective to give a copolymer resin having a polydispersity (Mw/Mn) within the range of about 5 to about 30. The resins, which are easy to make with even bulk polymerization, are particularly valuable, for example, as toner resins, thermoset resins, reactive plasticizers, and rheology modifiers.

摘要： A process for making hydroxy-functional resins based on acrylate, hydroxyalkylacrylate, and allyl monomers is disclosed. The key to the process is to add the hydroxyalkylacrylate monomer in an amount and manner effective to produce a resin that contains, without vacuum stripping, less than about 1 wt.% of residual unreacted allyl monomers. Eliminating the need to vacuum strip the allyl monomer reduces process costs and enables the synthesis of new resins. The hydroxy-functional resins are readily cross-linked with melamines, polyisocyanates, or epoxies to give thermoset polymers.
