POLYETHERAMINES WITH LOW MELTING POINT
20180009942 · 2018-01-11 ·

Described herein are substituted polyetheramines with a low melting point which are obtainable by condensation of at least two N-(hydroxyalkyl)amines to obtain a polyetheramine and subsequent reaction of at least one remaining hydroxy group and/or, if present, at least one secondary amino group of said polyetheramine with ethylene oxide and at least one further alkylene oxide to obtain a substituted polyetheramine. Uses of such substituted polyetheramines in fields of cosmetic formulations, as crude oil emulsion brakers, in pigment dispersions of ink jets, in electro paintings, or in cementitious compositions as well as methods wherein said substituted polyetheramines are used in said fields are described herein.

Polyether-modified polybutadienes and processes for preparation thereof

A process can be used for preparing polyether-modified polybutadienes. The process involves reacting at least one polybutadiene (A) with at least one epoxidizing reagent (B) to give at least one epoxy-functional polybutadiene (C). The at least one epoxy-functional polybutadiene (C) is then reacted with at least one hydroxy-functional compound (D) to give at least one hydroxy-functional polybutadiene (E). The at least one hydroxy-functional polybutadiene (E) is finally reacted with at least one epoxy-functional compound (F) to give at least one polyether-modified polybutadiene (G).

ALKYLENE OXIDE POLYMERIZATION USING ALUMINUM COMPOUNDS AND CYCLIC AMIDINES

Polyethers are prepared by polymerizing an alkylene oxide in the presence of a starter, an aluminum compound that has at least one hydrocarbyl substituent, and a cyclic amidine. The phosphorus-nitrogen base is present in only a small molar ratio relative to the amount of starter. The presence of such small amounts of cyclic amidine greatly increases the catalytic activity of the system, compared to the case in which the aluminum compound is used by itself. The product polyethers have low amounts of unsaturated polyether impurities and little or no unwanted high molecular weight fraction. Polymers of propylene oxide have very low proportions of primary hydroxyl groups.

ALKOXYLATED POLYALKYLENE IMINES OR ALKOXYLATED POLYAMINES WITH IMPROVED BIODEGRADABILITY

##STR00001##

Also described herein is a process for preparing such alkoxylated polyalkylene imines or alkoxylated polyamines as well as a method of using such compounds within, for example, cleaning compositions and/or in fabric and home care products. Also described herein are compositions or products that include the alkoxylated polyalkylene imine or the alkoxylated polyamine.

ALKYLENE OXIDE POLYMERIZATION USING ALUMINUM COMPOUNDS AND PHOSPHORUS-NITROGEN BASES

Polyethers are prepared by polymerizing an alkylene oxide in the presence of a starter, an aluminum compound that has at least one hydrocarbyl substituent, and a phosphorus-nitrogen base. The phosphorus-nitrogen base is present in only a small molar ratio relative to the amount of starter. The presence of such small amounts of phosphorus-nitrogen base greatly increases the catalytic activity of the system, compared to the case in which the aluminum compound is used by itself. The product polyethers have low amounts of unsaturated polyether impurities and little or no unwanted high molecular weight fraction. Polymers of propylene oxide have very low proportions of primary hydroxyl groups.
