Halogenated, flame-retardant polyesters are made by reacting certain unsaturated polyesters with chlorine, bromine, hydrogen chloride or hydrogen bromide. The polyesters are made by incorporating into the polyesterification mixture, one or more of (1) a low molecular weight mono-olefinic dicarboxylic acid and at least one of dicyclopentadiene, dimethyldicyclopentadiene, pentadiene, or a 5-lower alkylidene (2.2.1) bicyclohept-2-ene; (2) carbic, methylcarbic or tetrahydrophthalic acids or one of their anhydrides or (3) 2-butene-1,4-diol, 2-butyne-1,4- diol, 3 - cyclohexene - 1,1 - dimethanol, or allyl alcohol. Four methods for making the polyester, prior to halogenation, are described; (1) the "carbic" method in which the unsaturated dicarboxylic acid is reacted with the diene before the polyol is added; (2) the "beginning" method which comprises reacting the unsaturated acid, the diene and the polyol, in one step; (3) the "half-ester" method in which the unsaturated acid and the polyol are reacted before adding the diene and (4) the "end" method in which the unsaturated acid is polyesterified with the polyol, before adding the diene. In the examples, polyesters are prepared from (i) maleic anhydride, ethylene glycol, and dicyclopentadiene, (ii) maleic anhydride, propylene glycol and dicyclopentadiene, (iii) maleic anhydride, propylene glycol and carbic anhydride, (iv) maleic anhydride, ethylene glycol and carbic anhydride, (v) maleic anhydride, carbic anhydride, propylene glycol and ethylene glycol, (vi) maleic anhydride, dicyclopentadiene, ethylene glycol and diethylene glycol, and (vii) maleic anhydride, phthalic anhydride, and ethylene glycol. Those polyesters containing unsaturation may be mixed with a vinyl monomer (e.g. styrene) and the mixture copolymerized in the presence of benzoyl peroxide.

Filed: 1923-09-18
Abstract: 221,353. Shields, T. (Motorenfabrik Deutz Akt.-Ges.). Sept. 18, 1923. Cylinders receiving liquid fuel.-Two handactuated controls, the one controlling the fuel supply and the starting air admission valve, the other the supply of starting air, so interlock that it is impossible to turn on both fuel and starting air simultaneously. A lever P, Fig. 1, controls the fuel supply from pumps H, H<1> by means of the lever M and rod N, and moves the cam-shaft D by means of an arm Q. When the lever P is in the position shown, the fuel pumps are out of action and cams E and E' open the starting valves B, B<1> once during every cycle; when the lever is in the position shown by dotted lines, fuel is supplied by the pumps, and the starting valves remain closed. The supply of compressed starting air is controlled by a lever Z with which rotates a cam member Q<1>, Fig. 3. The rod N engaging with a groove Q<11> in the cam Q<1> locks the lever Z unless the lever P is in the position corresponding to no delivery of fuel, in which position a groove T, Fig. 2, in the rod N permits rotation of the cam Q'. When the lever Z is rotated to admit starting air to the valves, the entry of the cam Q' into the groove T prevents movement of the lever P.
