    摘要： Disclosed herein is a process for the preparation of a mixture of styrenated p-cresol species that is liquid at room temperature and has a viscosity of less than 40,000 cps at 25°C, wherein said process affords 2,6-distyrenated p-cresol assaying at 70% minimum by GC area percent, comprising reacting styrene with p-cresol at a molar ratio of 1.85 to 2.1:1, respectively, in the presence of an acid catalyst at elevated temperature, wherein said mixture comprises monostyrenated-p-cresol, distyrenated-p-cresol, and tristyrenated-p-cresol and exhibits an acid number of less than 0.1 mg KOH/gram.

    摘要： Flame retardants for polymer compositions which are mixtures including triaryl phosphate esters represented by the following formula (I) where R1-R15 can independently be located in the ortho, meta or para positions on their respective phenol rings and are, independently, H or branched or linear alkyl groups having 3 to 11 carbon atoms and the mole ratio of the alkylate to phenol in the mixtures is at least about 0.77, preferably greater than about 0.81, and most preferably greater than about 0.85. The higher alkylated mixtures of triaryl phosphate esters can be incorporated into polymer compositions alone or in combination with other flame retardants.

    摘要： A process for reducing the level of residual catalyst comprising one or more alkylhalide, alkoxyhalide, metal halide, metal oxyhalide, alkyl metal, alkoxy metal, boron compound and coordinated metal compound wherein the metal is a Group III, Group IV, Group V, Group VI and/or Group VIII metal, from a crude organic product (e.g., polyolefins, alkylated aromatic compounds, alkylated amines, etc.) comprising the residual catalyst is provided, the process comprising contacting the crude organic product with a solid adsorbent in an adsorbent system.
