Thereafter the composition is reacted with hydroxyalkyl(meth)acrylate and alkyldialkanolamine.
The fatty acid groups are substituted hydroxymethyl, N-hydroxyalkyl aminoalkyl or hydroxy-substituted ester groups.
(Hydroxyalkyl)urea crosslinking agents and compositions which utilize such crosslinking agents are disclosed.
The second monomer is a reaction product of a metathesized natural oil and a bis(hydroxyalkyl) amine.
The invention relates to formulations comprising an asphaltene-dispersing/-inhibiting additive based on oxazolidines derived from polyalkyl or polyalkenyl N-hydroxyalkyl succinimides.
The present application discloses a type of 2'-α-hydroxyalkyl taxel compounds with following formula (I), the compositions containing the same and uses thereof.
The present invention regards a three-step process for the synthesis of 5-(α -hydroxyalkyl) benzo[1, 3]dioxols.
The invention relates to coating materials containing α-(1'-hydroxyalkyl)acrylates, and to a method for the production and use thereof.
The present invention relates to symmetric diesters of hydroxyalkyl-4-hydroxy- tetraalkylpiperidine compounds and their use as light stabilizers.
