Michael P. Duncan - Schererville IN

Assignee:

Ferro Corporation - Cleveland OH

International Classification:

C08F 832

US Classification:

525368

Abstract:

The present invention provides a new and improved process for preparing a polybutene amine composition comprising the steps of reacting a chlorinated polybutene with an excess of at least one mole of at least one type of an amine compound per mole of the chlorinated polybutene at a reaction temperature of at least about 100. degree. C. ; neutralizing the reaction mixture with calcium oxide; and recovering the polybutene amine composition, the recovery process including the steps of removing the formed water and the neutralized and excess of the amine compound and removing inorganic solids using a non-aqueous separation technique such as filtration. During the neutralization step, water formation is kept to a minimum and no water is intentionally added to the process thereby minimizing resultant waste streams and/or undesirable by-products.
