Abstract: A method of making a polysilylether (PSE) polymer includes: cooling a solution of diethylamine to 0° C. under argon; adding cold dialkyldichlorosilane to form a first mixture; slowly warming the first mixture to form dialkylbis(diethylamino)silane; diluting the first mixture with hexane then filtering via cannula; evaporating the hexane and excess diethylamine; purifying the dialkylbis(diethylamino)silane under vacuum distillation; adding the dialkylbis(diethylamino)silane to a solution of diol dissolved in tetrahydrofuran to form a second mixture; heating the second mixture to 60° C. while reflux condensing, and cooling and concentrating the second mixture under vacuum to form a resultant mixture containing the polysilylether (PSE) polymer.

Abstract: A mobile communication tower comprising a trailer comprising a chassis, mounted on two or more wheels, a hitch, a plurality of chassis guy wire attachment points and a plurality of leveling mechanisms; a telescopic tower pivotally mounted on the trailer; a mechanism to raise and lower the tower; a plurality of tower guy wire attachment points located on the tower; and a plurality of guy wires each with an upper end attached to one of the tower guy wire attachment points and a lower end attached to one of the chassis guy wire attachment points.

Abstract: Laminate structures comprising a foamed polyurethane or polyisocyanurate resin core with a facer material uniformly adhered thereto with an adhesive material having functional groups capable of interacting chemically with isocyanate groups in the foamed resin core are disclosed. Suitable adhesive materials include .alpha.-olefin-acid copolymers, ethylene vinyl alcohol, polyimides, polyamines and phenolic resins. The bond between the foam core and the facer material has a peel strength of at least 1.5 lbs/in., preferably 5 lbs/in.
