Claims
- 1. An improved emulsifier for cationic bituminous emulsions comprising the reaction product of (a) an alkyl phenol of the general form ##STR5## where R represents a linear or branched alkyl group, (b) an aldehyde, and (c) a polyamine compound wherein the improvement comprises a polyamine compound formed as the reaction product of a polyamine and a compound selected from the group of a tall oil fatty acid, a polycarboxylic acid corresponding to the formula ##STR6## and a polycarboxylic acid corresponding to the formula ##STR7## wherein x and y are integers from 3 to 9, x and y together equal 12, at least one Z is a carboxylic acid group and any remaining Z is hydrogen.
- 2. An emulsifier for cationic bituminous emulsions comprising the reaction product of (a) an alkyl phenol of the general form ##STR8## where R represents a linear or branched alkyl group, (b) an aldehyde, and (c) the reaction product of a polyamine and a compound selected from the group of a tall oil fatty acid, a polycarboxylic acid corresponding to the formula ##STR9## and a polycarboxylic acid corresponding to the formula ##STR10## wherein x and y are integers from 3 to 9, x and y together equal 12, at least one Z is a carboxylic acid group and any remaining Z is hydrogen.
- 3. The emulsifier of claim 2 wherein said alkyl group comprises from 8 to 20 carbons.
- 4. The emulsifier of claim 2 wherein said alkyl phenol is selected from the group of octylphenol, nonylphenol and dodecylphenol.
- 5. The emulsifier of claim 2 wherein said aldehyde is formaldehyde.
- 6. The emulsifier of claim 2 wherein said polyamine is a blend of polyamines comprising aminoethylpiperazine and triethylene tetramine.
- 7. The emulsifier of claim 2 wherein said alkyl phenol is selected from the group of octylphenol, nonylphenol and dodecylphenol, said aldehyde is formaldehyde, and said polyamine is a blend of polyamines comprising aminoethylpiperazine and triethylene tetramine.
