The invention is an adhesive composition comprising: a) an isocyanate functional polyether base prepolymers having a z molecular weight average (Mz) of about 10,000 to about 80,000 g / mole; a carbon black having an average oil absorption number of at least about 80 to at most about 400 cubic centimeters of dibutyl phthalate per 100 grams of the carbon black; (c) reactive silicon in an amount from about 0.001% to about 10% by weight of the adhesive composition; and (d) one or more catalysts for the reaction of isocyanate with hydroxyl groups. The adhesive compositions of the invention surprisingly may have improved sag performance (i.e., decreased sag) when heated, while also making them more easily pumped.

A method of synthesizing a polymeric membrane is described in which a polymer, for example a polyvinylidene polymer or a terpolymer of ethylene, chlortrifluoroethylene and an acrylic monomer is heated and blended with a solvent. The solvent may be a high boiling latent solvent, for example butyl benzyl phthalate or tri iso nonyl trimellitate. The heated blend is shaped, which may involve casting on a supporting material such as a braided tube. Subsequently, the blend is cooled to thereby induce polymeric membrane formation on the supporting material.

The invention discloses a preparation method of dibutyl phthalate (DBP). The preparation method comprises the following steps: adding the raw materials including phthalic anhydride and superfluous butanol to a reaction kettle, adding concentrated sulfuric acid as a catalyst, controlling the temperature in the reaction kettle to be 0-150 DEG C, reacting for 16-20 hours, neutralizing the catalyst and unreacted phthalic anhydride with an alkaline solution after the reaction is completed, standing for layering and then carrying out washing with clear water several times. After alcohol-containing wastewater is collected, alcohols are recovered with a recovery tower and are reused. A lower ester layer after layering is heated to recover alcohols at reduced pressure (butanol is recovered by using a supergravity bed and is reused). After activated carbon is added for decoloration, the finished product of DBP is obtained through filter pressing by adopting a plate-and-frame filter press. The preparation method has the beneficial effects that the superfluous alcohol serves as a water-carrying agent, so that the esterification reaction is gradually carried through to the end, the technological process is simplified and the product quality is good; relative to a process of distillation in a rectifying tower, the preparation method has the advantages that the supergravity bed is used to recover butanol in the process, so that the energy consumption is effectively reduced and the process has better environment-friendly significance.
