of water, the catalyst and the free alcohol being removed from the product mixture following the reaction. Where alkoxysilanes with different organic functional groups are used, the desired aim is to obtain a distribution of the different substituents in the resultant siloxane oligomers which is ...
Examples of organic solvents that may be mentioned include linear or branched and preferably saturated monoalcohols or diols, comprising 2 to 10 carbon atoms, such as ethyl alcohol, isopropyl alcohol, hexylene glycol (2-methyl-2,4-pentanediol), neopentyl glycol and 3-methyl-1,5-pentanediol, but...
In addition, it has been found that the flame retardancy of the various phosphinates in thermoplastic polymers can also be distinctly improved by addition of small amounts of organic or mineral compounds that do not contain any nitrogen, and that the additives mentioned can also improve the flame...
Owing to the basic character of their nitrogen atoms, the compounds I, II and III are capable of forming salts or adducts with inorganic or organic acids or with metal ions. Examples of inorganic acids are hydrohalic acids such as hydrofluoric acid, hydrochloric acid, hydrobromic acid and hydri...
especially two-component systems. The coating materials of the invention may also be formulated on the basis of organic solvents (conventional coating materials) or aqueous media (aqueous coating materials). Alternatively, they may be substantially or completely solvent-free and water-free liquid coatin...
wherein Q is a polyether group comprising about 10 propenoxy units, and the weight ratio of cationic to nonionic surfactant is from about 1.5:1 to about 1:50, respectively. 7. An element as in claim 4, wherein the cationic surfactant is perfluorooctylsulfonamido-(N-propyl-3-N,N,N-trim...
Suggested is an antimicrobial mixture comprising or consisting of (a) at least one monocyclic sesquiterpene alcohol, (b) at least one active selected from the group consisting of 4-hydroxyacetophenone, sorbitan caprylate, cocamidopropyl PG-dimonium chloride phosphate, tetrasodium glutamate diacetate, glycer...
Bentonite clay has already improved the organic selectivity of glassy polymers [11]. When bentonite is incorporated into the polymer matrix, three types of materials can be generated depending on the how the clay particles are dispersed in the polymer matrix as shown in Scheme 1 [12]. Scheme...
