Abstract: An isocyanate terminated prepolymer has been discovered that has sufficiently low glass transition temperature (Tg), necessary rheological properties and mechanical properties that allows for the making of adhesive compositions useful for bonding substrates into larger structures (e.g., windows in vehicles and buildings) with minimal or no plasticizers. The polyether prepolymer comprises a polyisocyanate reaction product of a polyisocyanate having an isocyanate functionality of greater than 2 and a polyether monol having an average molecular weight (Mw) of 1000 to 2000 g/moles and said prepolymer having: (i) a weight molecular weight average (Mw) of about 2000 to about 30,000 g/mole, (ii) a free isocyanate content of 0.8% to 4% by weight of said prepolymer, and (iii) viscosity of 1000 to 50,000 centipoises.
