Abstract
Abstract The invention provides a process for the Mannich condensation reaction of oxidized olefinic polymers. The condensation reaction is carried out in the presence of about 0.01 to 25.0 weight percent of an oil soluble phenol based on the neat polymer. The phenols improve the processing and properties of the oxidized oil soluble Mannich reaction product.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
111 words
A process of producing Mannich compound which comprises reacting a high molecular weight oxidized amorphous addition polymer of essentially olefinically unsaturated monomers, a formaldehyde yielding reactant, at least one amine selected from the group consisting of alkyl primary or secondary aliphatic monoamines having from about 2 to about 12 carbon atoms and a polyalkylene polyamine of the general formula: NH 2 --[(CH 2 ) z NH]-- x H wherein z is an integer from about 2 to about 6 and x is an integer from about 1 to about 10 and a phenolic compound, wherein the phenol compound is present at about 0.01 to 25.0 weight percent based on the polymer.
Claim 2
Dependent Claim
111 words
A process of producing Mannich compound which comprises reacting a high molecular weight oxidized amorphous addition polymer of essentially olefinically unsaturated monomers, a formaldehyde yielding reactant, at least one amine selected from the group consisting of alkyl primary or secondary aliphatic monoamines having from about 2 to about 12 carbon atoms and a polyalkylene polyamine of the general formula: NH 2 --[(CH 2 ) z NH]-- x H wherein z is an integer from about 2 to about 6 and x is an integer from about 1 to about 10 and a phenolic compound, wherein the phenol compound is present at about 0.01 to 25.0 weight percent based on the polymer.
