    摘要： Dispersions of hydrophobic substance e.s. resin emulsions, usually having a relatively low average particle size can be continuously and speedily prepared by feed a hydrophobic substance in the liquid state into at least two static mixers, arranged in a series. The resin is introduced at a temperature above 50 degrees C. but below its degradation temperature of hydrophobic substance and water under pressure is introduced into the first mixer. The mixture of resin and water is passed to another mixer maintained at a temperature lower than that prevailing in the first mixer and below the boiling point of water. Optionally aqueous solution of surfactant under pressure instead of water is introduced into the first mixer and optionally aqueous surfactant is introduced into the second mixer.

    摘要： High softening point resins are prepared by a process which comprises polymerizing in the presence of a Friedel-Crafts catalyst a mixture of (1) a feedstock comprising C.sub.5 olefins and diolefins, C.sub.6 olefins and diolefins or a mixture of C.sub.5 and C.sub.6 olefins and diolefins, said feedstock being obtained from the steam-cracking of petroleum feedstock and (2) a polymer obtained by the thermal or cationic polymerization of dicyclopentadiene, an alkyl cyclopentadiene dimer, a codimer of cyclopentadiene with an alkyl cyclopentadiene, a codimer of cyclopentadiene or an alkyl cyclopentadiene with a C.sub.5 or a C.sub.6 conjugated linear or non-cyclic diolefin, or a mixture of said dimer and codimers. The resin may be mixed with rubber to make a pressure-sensitive adhesive.

    摘要： Resin emulsions are prepared by forming an emulsion of an aqueous solution of an unsaturated material reactive with the resin in the liquid resin, causing the material and the resin to react and adding sufficient water to invert the emulsion to form an emulsion of the reacted resin in water to produce emulsions with improved mechanical stability useful as tackifiers in water-based pressure-sensitive adhesive coating materials in high speed coating lines giving reduced deposits and extended coating times.

    摘要： Low softening point resins are prepared by a process which comprises polymerising using a Friedel Crafts catalyst:(1) a petroleum resin feed comprising C.sub.5 olefins and C.sub.5 diolefins or a mixture of C.sub.5 and C.sub.6 olefins and diolefins, said feed being obtained from the cracking of petroleum feedstock and being subjected to thermal soaking at a temperature of 100.degree. C to 150.degree. C, and(2) a branched chain reactive aliphatic olefin or an oxygenated transfer agent.Preferred additives are diisobutene or U.O.P. olefins. The polymerization may take place in the presence of a C.sub.8 to C.sub.10 unsaturated aromatic compound.
