TL;DR: In this article, an improved process for selectively preparing a predominantly noncyclic polyalkylene polyamine compound is disclosed wherein an alkyleneamine compound was contacted with an alkanolamine compound in the presence of a catalytically effective amount of a phosphorus-containing substance at a temperature of from about 250° to about 350° C under a pressure sufficient to maintain the mixture essentially in liquid phase.

TL;DR: In this article, Terephthalic esters are made to remain in a liquid form by reacting recycled or scrap polyethylene terephthalate (PET) with diethylene glycol and one or more oxyalkylene glyols.

TL;DR: A mixture of aromatic polyester polyols useful in preparing rigid foams is described in this article, where the polyols are made by first reacting recycled polyethylene terephthalate (PET) scrap with an alkylene glycol to form a reaction product which is then reacted with a propylene oxide.

TL;DR: In this paper, a mixture of aromatic polyols containing ester functionalities suitable for use as polyol extenders in rigid foams prepared by reacting dibasic acid residues with an alkylene glycol residue, the reaction product of which is reacted with recycled polyethylene terephthalate is described.

TL;DR: A detergent additive represented by the formula: R--[O--CH.sub.2] as mentioned in this paper, where R is a hydrocarbyl radical having from 8 to 18 carbon atoms and y is about 2 to 6.
