    摘要： A process for the production of largely amorphous polyalphaolefins with a narrow molecular weight distribution is provided where the products exhibit the following features:softening point between 70.degree. and 40.degree. C.;melt viscosity (190.degree. C.) between 1,000 and 100,000 mPas;density less than 0.90 g/cm.sup.3 ;needle penetration between 5 and 50 0.1 mm; andmaximum molecular inhomogeneity 6.These polymers are obtained by a radical decomposition performed at high temperatures on copolymers based on C.sub.4-10 alpha-olefins, propene and optionally ethene. The products are suitable for use as hot melt adhesives as well as for heavy coating compounds.

    摘要： A protective material, based on poly-.alpha.-olefins, capable of easy application in molten form, is distinguished by a balanced pattern of properties, good adhesion and good recycling capability. The present protective materials contain (I) not less than 50% by weight of one or more largely amorphous poly-.alpha.-olefins, composed of (a) 3 to 75% by weight of one or more .alpha.-olefins containing 4 to 10 carbon atoms, (b) 25 to 95% by weight of propene, and (c) 0 to 20% by weight of ethene; (II) not more than 30% by weight of other olefin homo- and copolymers which may be either largely amorphous or preferably partially crystalline; and (III) not more than 40% by weight of additives which are standard in the plastic sector. Such protective materials can be used in particular in the underfloor region of motor vehicles.

    摘要： Wax-like esterification products derived from optionally partially saponified hard paraffin oxidation products and mono- or multivalent alcohols, which are suitable particularly as lubricants for plastics processing, are formed in the melt with particularly high degrees of esterification and without discolorization. The conversion is conducted at 160.degree. to 220.degree. C. in the presence of zinc salts such as zinc stearate.
