Abstract

The structural requirements of pour-point depressants as fixed by studies of acrylic polymers are indicated to be an alkyl side chain length of at least 12 carbons and a degree of polymerization commensurate with suitable over- all physical properties. Polyhexadecylene phthalate was prepared which was capable of lowering the pour point of an untreated MIL-L-6082A AN-)-* 1100 grade oil 30 F. Light microscopical and x-ray diffraction studies of the action of additives on blends of synthetic n-paraffin waxes in dewaxed oil support the theory that pour-point depressants do not enter the crystal lattice but act by means of a surface phenomenon. A review of the literature and an evaluation of commericial additives are given.
