  • Patent number: 7608670
    Abstract: An improved curable formaldehyde-free binding composition is provided. Such curable composition comprises the reaction product of a polyanhydride and a polyol crosslinker and a lower molecular weight anhydride. Initially, the polyanhydride is modified through reaction with a polyol (e.g., a glycol or an alkanolamine) and subsequently is grafted with the lower molecular weight anhydride (e.g., maleic anhydride) to form a water-soluble or water-dispersible curable reaction product. The composition is well suited for binding fibrous materials (e.g., a mat of glass fibers) or for bonding together non-fibrous materials. The binder composition displays an advantageous viscosity so as to facilitate a flowable application with ease combined with an adequately high molecular weight to satisfactorily undergo service as a binder following curing even when harsh environmental conditions (e.g.

    Abstract: A monomer having a pair of hydroxy groups held in a fixed relationship (e.g. a dihydroxybenzene) is diesterified with a compound having a polymerisable group, e.g. to form a diacrylate. After polymerisation with a crosslinker, the polymer is hydrolysed. The dihydroxy-monomer is removed, leaving a polymer with pair of carboxyl groups held in spatial relationships determined by the dihydroxy monomer. Thus a range of subtly different polymers can be prepared by using different dihydroxy-monomer templates. The polymers are desirably swellable. They can be used as selective binding materials, e.g. in chromatography or analysis.

  • Patent number: 7375163
    Abstract: Described are polymers and cement admixtures which reduce drop in fluidity with time. Said admixture comprises at least one polymer of the present invention and at least one polymer A. The polymer of the present invention comprises side chains of which at least 10 weight-% can be cleaved in alkaline medium. The polymer of the present invention is an acrylic polymer which comprises side chains connected to the backbone by ester linkages. These side chains may be alkyl, hydroxy alkyl, cycloalkyl or polyoxyalkylene groups. Polymer A is a cement dispersing agent. The combination of polymer A with the polymer of the present invention in a weight ratio of 0.1:10-10:1, and preferably 1:10-10:1 reduces the drop in fluidity with time of cementitious compositions.

  • Publication number: 20080103262
    Abstract: A method for the production of packaging material systems for technical and pharmaceutical individual doses uses acid-catalyzed acetalization reaction of polyvinyl alcohol with vinyl alcohol copolymers (PVACL) produced with starch or starch derivatives in conjunction with destructuring agents. In the method, vinyl alcohol copolymers (PVCL) which contain water and which are soluble in cold water are produced either beforehand or after from the films and destructuring agents are added such that the hydrogen bridges between the polymer chains are fully or partially interrupted and that the films of vinyl alcohol copolymers thus prepared are subsequently heated to temperatures below the melting or expansion intervals thereof and are further processed in a sealing process using pressure for the production of a sealing seam for packaging in the form of individual doses.

  • Patent number: 7342074
    Abstract: Polyhydroxy curable fluoroelastomers that are substantially free of nucleophilic endgroups are grafted with a monophenol having at least one pendant group. The resulting grafted fluoroelastomers retain most of the properties of the original elastomers including excellent pre-vulcanization characteristics, while incorporating pendant groups which may be used for further modification, crosslinking or for changing the physical properties (e.g. Tg) of the fluoroelastomer.

  • Patent number: 7339007
    Abstract: A process for forming an ene reaction product wherein an enophile, such as maleic anhydride, is reacted with reactive polyalkene having a terminal vinylidene content of at least 30 mol. %, at high temperature in the presence of a free radical inhibitor. The polyalkenyl acylating agents are useful per se as additives in lubricating oils, functional fluids, and fuels and also serve as intermediates in the preparation of other products (e.g., succinimides) useful as additives in lubricating oils, functional fluids, and fuels. The presence of the free radical inhibitor during the high temperature reaction results in a reaction product that is low, or substantially free from sediment.
