Patent number: 7390855Abstract: A new family of concrete admixture additives can be derived from reacting a mixture of olefins/cyclic olefins-maleic anhydride copolymers and methoxy polyethylene glycol amines and/or polyethylene glycol monoalkyl ethers, or a mixture of styrene-maleic anhydride copolymers and methoxy polyethylene glycol amines and/or polyethylene glycol monoalkyl ethers, or a mixture of styrene-olefins/cyclic olefins-maleic anhydride terpolymers and methoxy polyethylene glycol amines and/or polyethylene glycol monoalkyl ethers. These reactions lead to formation of a kind of carboxylic salt containing polymer, which can be used alone in concrete. Only a small amount of this substance is needed to provide excellent water reduction, high concrete flowability and high early strength.Type: GrantFiled: November 6, 2007Date of Patent: June 24, 2008Assignee: Taiwan Gwan Chian Industrial Co., Ltd.Inventor: Theresa Tsai

Patent number: 7232863Abstract: Disclosed is a method for making nongelled functional addition polymers from linear unsaturated anhydrides. The method subjects a linear unsaturated anhydride compound, an active hydrogen compound, and an epoxide compound to reaction conditions such that each of the following three reactions occur: (i) polymerization of polymerizable C?C bonds, (ii) ring opening of an anhydride functional group of the linear unsaturated anhydride compound by the active hydrogen compound to create an acid functional group, and (iii) reaction of the acid functional group resulting from the anhydride ring opening with the epoxide compound. At the time of reaction (iii), the acid functional group resulting from the anhydride ring opening may be selected from an ethylenically unsaturated monomer, a polymer, or both. In one embodiment, the method does not include the physical removal of any acid functional monomers or polymerization products. Also disclosed are a curable coating composition and a coated substrate.Type: GrantFiled: October 1, 2004Date of Patent: June 19, 2007Assignee: BASF CorporationInventors: Walter H. Ohrbom, Donald H.

Patent number: 7230048Abstract: A continuous polymerization process for producing reactive polymers comprises continuously charging into a first reaction zone at least one functional monomer and polymerizing the monomers to produce a first polymeric product having at least one functional group. This first polymeric product is then continuously directly charged into a second reaction zone together with at least one modifier reactant having a functional group that is complementary to the functional group of the first polymeric product. At least a portion of the modifier reactant reacts with at least one of the functional groups of the first polymeric product to produce a second polymeric product which incorporates at least a portion of the modifier reactant, such that the second polymeric product is a reactive polymer.Type: GrantFiled: August 25, 2000Date of Patent: June 12, 2007Assignee: BASF CorporationInventors: David D.
