## Abstract A series of waterβbased polyurethane dispersions were synthesized by the polyaddition of isophorone diisocyanate, poly(oxytetramethylene) glycol, and dimethylol propionic acid as prepolymers, which were endβcapped and crosslinked with 3βaminopropyl trimethoxysilane (APTMS) to produce si

Epoxy resins are increasingly finding applications in the field of structural engineering. A wide variety of epoxy resins are available, and some of them are characterized by a relatively low toughness. One approach to improve epoxy resin toughness includes the addition of either a rigid phase or a
Starch-based polyurethane foams were synthesized by reacting a mixture of starch and polycaprolactone triol with an aliphatic diisocyanate, in the presence of water as blowing agent. Some foams were also prepared by adding a certain amount of polyethyleneglycol. The reaction kinetics is affected by
