The water absorption device consists of a sintered glass funnel and a 10 mL pipette. The funnel and pipette were connected by a rubber tube to control the sintered glass funnel, which was 38 cm away from the table, 37.5 cm from the head of the pipette to the table, meaning that...
Process for the preparation of water-dispersible polyurethanes with an essentially linear molecular structure by reaction of organic diisocyanates with organic compounds that are dysfunctional in the sense of the isocyanate polyaddition reaction, carrying hydrogen atoms reactive with respect to the ...
However, these previous investigations can only increase the dispersion of nGO in limited organic solvent or only aqueous solution but be still unable to guarantee the stable and uniform distribution of nGO in the matrix material, meaning that the aggregation and settlement are still possible to ...
These polyesters form stable dispersions in water, are coatable by machine without undesirable blocking of spool-wound materials, and dry to form a water-insoluble adhesive film which is heat-activatable to form seals insensitive to high humidity or the presence of aqueous processing composition. ...
water-based dendritic polymer coating, the coating comprises a fluorine-containing dendritic polymer having at least one pendant fluorocarbon moiety and at least one pendant anionic moiety. Presumably, the presence of the anionic moieties improves the dispersibility of the dendritic polymer in water. ...
Enhanced isocyanates can be obtained by making at least one isocyanate react with at least one polyethylene oxide polyether alcohol and at least one compound having formula (I) wherein the indices and substituents have the meaning given in the description.JANSEN, BERNHARD, DIPL.-CHEM. DR., ...

Improved delivery and bioavailability of the active ingredient in agrochemical compositions, especially of water insoluble actives for example sulphonyl ureas, to achieve a desired agrochemical effect is desirable. It is also desirable to achieve this effect in as cost effective manner as possible and ...
The invention relates to a pulverulent adhesive for textile reinforcing plies which is dispersible in water, comprising: a) 85 to 97% by weight of at least one at least partially capped, low-molecular isocyanate
, R having the meaning given above; or an amido group wherein R2, m and n have the meanings given above. The halogenation is generally carried out by contacting the vinyl ester with free halogen in the presence of a solvent, if necessary, e.g. methylene dichloride. The halogen is pref...
