Study on epoxy resins adhesives by amine-terminated polyether as curing agent;

Using the mixture of phenal and aldenhyde-modified ethylene diamine or diethylenetriamine and amine-terminated polyether as the curing agent.

It is easy to consider that the reactivity of each amine is similar, because both of polyethenoxyamines and isophoronediamine are diamine and because amino groups and their vicinity groups are similar in molecure structures.

In this dissertation, the methods and mechanisms of toughening EP have been reviewed, and a view to prepare a kind of flexible, elastic,transparent epoxy adhesive, having high elongation at break and satisfactory mechaincal properties, by flexible chain structure used polyetheramines.

A kind of polyetheramine was synthesized by high pressure catalytic amination.

Waterborne polyurea was prepared by IPDI,polyetheramines and the sodium salt of N-(2-aminoethyl) -2-aminoethane sulfonic acid(AAS) as main raw materials only in need of 30 minutes without heating.

Advance of polyethermaide reisn(PEAR);

The synthesis and properties of the neat resin of polyetheramide resin (PEAR) are introduced.

Morphology and mechanical properties of epoxy resin network containing polyoxypropylene polyamine;
