Abstract
Polycarbonates of molecular weight 700-5000 and having terminal hydroxyl group are made by heating 1 mole of a cyclic glycol carbonate with 0,01-0,20 moles of an organic compound having at least two active-hydrogen atoms (other than a polyhydric alcohol) at above 100 DEG C. and in the presence of a basic substance as catalyst. Heating is preferably effected at 150 DEG -225 DEG C. in an autocalve under autogenous pressure, e.g. up to 3000 p.s.i.g. Specified glycol carbonates are ethylene-, 1,2-propylene-, 1,2-butylene-, 2,3-butylene-, vinyl ethylene-, methyl vinylene-, ethyl vinylene-, propyl vinylene-, and dimethyl vinylene carbonates. The active-hydrogen compound may have its active-hydrogen atoms in the form of amino, mercapto, carboxylic or carbamate groups and specified compounds are di-hexamethylene diamines, piperazine, 1,2-ethanedithiol and ethanolamine. Specified catalysts are alkaline reacting carbonates, bicarbonates and hydroxides, trisodium phosphate, and aliphatic and heterocyclic tertiary amines. The polycarbonates may be reacted with polycarboxylic acids (e.g. phthalic, adipic, succinic, maleic and fumaric acids) to form alkyd resins useful as moulding, laminating, coating and impregnating agents. They may be reacted with isocyanates to form urethanes or polyisocyanates (e.g. toluene diisocyanate) to form polyurethanes. Foams are made by effecting the polyurethane forming reaction in the presence of a foaming agent (e.g. water) and, if desired, a cross-linking agent (e.g. glycerol). Examples describe the manufacture of polycarbonates by heating ethylene carbonate with piperazine or ethane dithiol in the presence of potassium carbonate.ALSO:Polyurethane foams are made by reacting (1) a polycarbonate resin of molecular weight 700-5,000 obtained by heating 1 mole of a cylcic glycol carbonate with 0,01-0,20 moles of an organic compound having at least 2 active hydrogen atoms other than a polyhydric alcohol (see Group IV(a)), (2) a polyisocyanate, e.g. toluene diisocyanate and (3) a foaming agent, e.g. water. The resulting elastic foam serve as crash pads or upholstery pillows. Rigid foam, obtained by including a cross-linking agent (e.g. glycerol) in the reaction mixture are useful as insulating materials in aircraft and as insulation for heating and cooling ducts.
