  • Patent number: 4623711
    Abstract: A liquid polymer composition curable to a solid elastomer having good thermal stability which contains a mercaptan terminated disulfide polymer of the formula HS(RSS).sub.m R'SH wherein R is --C.sub.2 H.sub.4 --O--CH.sub.2 O--C.sub.2 H.sub.4 --; R' is a member selected from the group consisting of alkyl of from 2 to 12 carbon atoms; alkyl thioether of from 4 to 20 carbon atoms; alkyl ether of from 4 to 20 carbon atoms and one oxygen atom; alkyl ether of from 4 to 20 carbon atoms and from 2 to 4 oxygen atoms each of which is separated from the other by at least 2 carbon atoms, alicyclic of from 6 to 12 carbon atoms and aromatic lower alkyl; and the value of m is such that mercaptan terminated disulfide polymer has a molecular weight of between 1,000 to about 4,000. The method includes cleaving a polymer having disulfide linkages with an organic dimercaptan in the presence of an organic amine.

  • Patent number: 3989228
    Abstract: A static mixing chamber for mixing multi-component compositions has the provision of having the mixing chamber at the outlet of the feed lines. A valve is at the outlet end of the chamber. By having the chamber near the outlet end, a large pressure drop across the chamber is insured. Moreover, the valve at the end of the chamber insures that the large pressure drop will be maintained even during start-up of dispensing. By increasing the pressure drop over the chamber, mixing therethrough has been greatly enhanced. Therefore, a smaller mixture is required for effective mixing. The result in small size makes the static mixer capable of being hand held, in the form of a dispensing gun and the valve actuator is part of the dispensing gun so that the valve can be operated by the same hand that is holding the gun.
