Abstract: Polycarbonates having a molecular weight of 700-5000 and hydroxyl numbers of 20 to 170 are made by heating 1 mol. of a cyclic glycol carbonate with 0.01-0.20 mols. of a polyhydric alcohol at above 100 DEG  C. in the presence of a basic substance as catalyst.  Reaction is preferably effected in a closed vessel at a pressure up to 3000 p.s.i.g. and at 150-225 DEG  C.  The polyhydric alcohol may be added to the reaction mixture as such or may be formed in situ by adding water which reacts with the glycol carbonate to form a dihydric alcohol.  Specified glycol carbonates are ethylene, 1,2-propylene, 1,2- or 2,3-butylene, vinyl ethylene, methyl vinylene, ethyl vinylene, propyl vinylene and dimethyl vinylene carbonates. Specified polyhydric alcohols are aliphatic glycols containing less than 10 carbon atoms and no more than 4 ether linkages; also glycerol, trimethylolethane, trimethylol propane and pentaerythritol. Specified catalysts are various inorganic carbonates, bicarbonates, hydroxides and phosphates and various organic tertiary amines.  The polycarbonates may be reacted with polycarboxylic acids (e.g. phthalic, adipic, succinic, maleic or fumaric acids) to yield alkyd resins suitable for moulding, laminating, coating or impregnating. They may be reacted with isocyanates to yield urethanes and polyisocyanates to yield polyurethane rubbers.  Elastic or rigid foams are made by reaction of the polycarbonates with a polyisocyanate, water and if desired, glycerol (see Group V). Examples describe preparing polycarbonates by heating ethylene carbonate with ethylene glycol, diethylene glycol or water.ALSO:Polyurethane foams are made by reacting a hydroxyterminated polycarbonates of molecular weight 700-5,000 with a polyisocyanate in the presence of a foaming agent, e.g. water.
