摘要:
Aqueous curable polymer dispersion comprising a polyester and/or polyurethane and a polymeric product having a Tg from 25.degree.-100.degree. C. obtainable by free-radical polymerisation of a mixture of (a) an olefinic monomer free from epoxy and epoxy reactive groups, (b) a monomer and/or oligomer having at least two epoxy groups and (c) a group reactive towards epoxy groups.
摘要:
A strategy is described for delivering information items to a client device in response to download events. At some time later, the client devices present the information items to users in response to respective delivery events. The strategy is particularly beneficial in those environments characterized by non-real-time request-response performance, such as network environments characterized by significant levels of latency and/or intermittent connectivity. The strategy overcomes this non-real-time performance by downloading relevant information items to users before the items are delivered, thus making the information items more readily available when actually needed. Other provisions are provided for ensuring that valid accounting is applied to the delivery of information items, and for allocating revenue based on this accounting. In one implementation, the information items correspond to advertisements.
摘要:
Compositions comprising an oligomer which (a) on average comprises at least one in-chain residue of the general formula ##STR1## wherein Ar.sup.1 is an aromatic group, R.sup.1 is hydrogen or a hydrocarbyl group, X is a group which activates Ar.sup.1 to electrophilic attack, and Y.sup.1 is an organic residue bearing a carboxyl substituent; ad (b) has one or more pendant and/or terminal acyloxymethyl groups are described. They may be used in dental, electronic and electrical applications.
摘要:
Process for making a polymer with desired groups Y comprising reacting a precursor polymer having carbon- or nitrogen-bound --NH.sub.2 and/or --NH-- groups with at least one compound having a single enolic carbonyl group and at least one group Y. Also the polymer itself and a composition containing it.
摘要:
An aqueous selfcrosslinkable coating composition which comprises an aqueous dispersion of at least one polymer having chain-pendant amine groups and certain selected non-polymeric ketone-containing compounds, particularly acetoacetates and acetoacetamides, whereby selfcrosslinking is effected, often at ambient or low temperatures, during and/or after film formation.
摘要:
A method and system for allowing a regional service merchant that is outside of a given geographical boundary, but services inside the geographical boundary, to be included in a result set of a search directed to a location inside the geographical boundary. Text and/or glyphs are returned along with the regional service merchant's business listing so as to explain to a user why a business not physically residing in the search area has been included in the result set. An application programming interface ensures that, if a business is listed as a regional service merchant, then the text and/or glyph is stored in association with the business listing.
摘要:
A cohesive polymer matrix comprising a matrix polymer and a coated particulate filler dispersed therein, characterized in that the matrix polymer is an emulsion rubber, and the filler is coated at least in part with a composition comprising an organic coating polymer of number average molecular weight of 4,500 to 200,000 which contains an acidic group (or a precursor thereof) and an unsaturated group, optionally linked to the matrix polymer and a process for its production.
