摘要:
2-benzyl-1-alkanol polyglycol ethers having the formula: ##STR1## in which R.sup.1 is a C.sub.6 to C.sub.22 alkyl group; R.sup.2 is a C.sub.2 -C.sub.6 alkylene group; and n is an integer from 1 to about 100.The products are produced by heating a mixture of a ratio of an alcohol having the formula:R.sup.1 --CH.sub.2 --CH.sub.2 OHwherein the symbol R.sup.1 has the same meaning as above with a ratio of from about 1 mole to about 10 moles, preferably 1 to 3 moles, of benzyl alcohol to a temperature of from about 180.degree. C. to 250.degree. C. in the presence of an alkali metal compound, and optionally a hydrogenation catalyst; separating the excess benzyl alcohol from the mixture and alkoxylating the alcohol thus obtained.The polyglycol ether are used as wetting agents, dispersants, emulsifiers and detergents.

摘要:
The invention relates to phenols which contain a number of aromatic nuclei and in which the bridge formation of these nuclei is in the meta-position to the OH groups. These phenols have the formula I, wherein R.sup.1, R.sup.2, R.sup.3 and R.sup.4 are as defined in claim 1.The novel phenols are most suitable for use as stabilizers for organic polymers and lubricants and have particularly good color properties.

Partial esterification products of polyglycerols and branched chain fatty acids are useful in cosmetic lipsticks. The polyglycerol partial esters, particularly those derived from isostearic acid, are useful substitutes for all or part of the castor oil in the lipstick formulation.
摘要:
The invention relates to a method for producing radiation-curable alkenyl ether polyols, to radiation-curable alkenyl ether polyols produced using the method according to the invention, and to the use thereof for the synthesis of radiation-interlinkable oligomers or polymers by means of polyaddition reactions or polycondensation reactions, in particular for the synthesis of radiation-curable polyesters, polyethers, polyurethanes and polyureas, particularly preferably UV-curable polyurethanes. The invention also relates to radiation-curable polyurethane polymers that are obtained by reacting at least one alkenyl ether polyol according to the invention with a polyisocyanate.
