International Classification:

C07C 213/04

US Classification:

564475, 564477

Abstract:

The present invention generally relates to a process for preparing alkoxylated alkylamines and/or alkyl ether amines. The process consists of two stages and utilizes a catalyst with a multiple-charge counterion. The alkoxylated alkylamines and alkoxylated alkyl ether amines prepared by the process possess the peaked ethoxylation distribution and contain less hazardous by-product.

Filed:

Nov 19, 1979

Appl. No.:

6/095574

Inventors:

William I. Ferree - Dallas TX
Giao V. Nguyen - Dallas TX

Assignee:

Liquid Paper Corporation - Dallas TX

International Classification:

C08K 517

US Classification:

260 297H

Abstract:

An erasable writing medium composition suitable for use in porous tip and ballpoint pens is provided. The erasable writing medium comprises an emulsion having a continuous water phase and discontinuous phase that comprises a styrene-butadiene latex copolymer. The colorant or dye is dissolved in the continuous phase and also is believed to form a surface layer on the discontinuous phase particles. Upon drying, the colorant is captured by the copolymer thereby preventing the colorant from being absorbed by the writing surface.
