Abstract
Novel boron alkyl compounds which are esters of a fatty acid or a fatty alcohol and which have at least one boryl radical or organoboron radical attached thereto. These boron alkyl compounds can be used to harden monomer adhesives, and are stable and active even when exposed to air.
Claims30
A boron alkyl compound comprising the addition product of an unsaturated ester, having double bonds of which about 30 to 100% are hydroborated with a boron compound;
- said ester being either (a) comprised within at least one naturally occurring unsaturated fat or oil or mixture thereof having about 12 to 22 carbon atoms, or (b) at least one synthetic reaction product of a C.sub.12-22 hydroxy or non-hydroxy fatty acid or alcohol which has at least one olefinic double bond with a complementary polyfunctional alcohol or carboxylic acid containing from 2 to 10 carbon atoms in addition to any carboxyl radicals present;
- and said ester (a) or (b) having an iodine number between about 5 and 130;
- said boron compound being at least one borane or organoborane having at least one alkyl, cycloalkyl or aryl radical with from 1 to 25 carbon atoms;
- and wherein said boron alkyl compound has enhanced stability in the presence of air and is soluble in reaction systems containing monomers having polymerizable double bonds.
