  • Patent number: 9150708
    Abstract: An adhesive based on a polychloroprene dispersion is characterized in that a buffer system comprising at least one acid compound and glycerin is included in order to activate and stabilize the adhesive. A freeze-thaw stability of the adhesive is achieved by surprisingly high proportions of glycerin; however, a good initial adhesion is simultaneously ensured. The glycerin proportions range from 8-50 wt. %, preferably 14-40 wt. %, particularly preferably 22-30 wt. %. An organic acid is preferably used as the acid compound.

  • Patent number: 4448909
    Abstract: A method for determining the concentration of additives in a compounding process by measuring the capacitance and dissipation factor (tan.delta.) of the mixture and converting such values to the concentrations of the additives. This method may also be utilized to determine the concentration of the polymers in the mixture. This method is preferably applied to a compounding process of blending polyphenylene oxide and polystyrene thermoplastic resins and is preferably applied to a continuous compounding process of these resins to determine therein the concentration of an aryl phosphate ester flame retardant.
