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.

Provided are a polyol glyceryl ether, and a multi-armed polyethylene glycol and the multi-armed polyethylene glycol active derivative prepared using the same. The multi-armed polyethylene glycol is formed by polymerizing ethylene oxide with the polyol glyceryl ether as an initiator, and has the structure of general formula II, wherein B is a polyol group, n is an integer between 3 and 22, PEG is the same or not the same (OCH.sub.2CH.sub.2).sub.m, and the average value of m is an integer between 3 and 250. The multi-armed polyethylene glycol has a relatively low poly-dispersity and a relatively high determined molecular weight. Also provided is a conjugate of the multi-armed polyethylene glycol active derivative and pharmaceutical molecules, a pharmaceutical composition comprising the conjugate, and a gel formed by the multi-armed polyethylene glycol active derivative. The gel can be used to prepare a sustained-release drug for prolonging the time of the drug action.
