RUBBER BLEND CURED WITH SULFUR/ PEROXIDE/ZINC OXIDE/ ACCELERATOR

摘要

This invention relates to the polymer additives which can be used for the inhibition of paraffins and the object of the properties of the discharge of the crude oils and the compositions containing the crude oils and additives. With the additive according to the invention consists in the form of a polymer units arising of one or more alkyl esters of monocarboxylic acids unsaturated, of one or more compounds a, b - dicarboxylic unsaturated in the form of a diacid, alkyl diester lightweight or anhydrous and one or more monomers has ethylenically unsaturation of the general formula: ch czzdans which z and z are identical or different represent the 1996, a halogen, a radical hydrocarbon saturated, unsaturated or aromatic, an ester or ether. The compositions containing a crude oil and 5 has 4000ppm then 100 has 1500ppm of additive have pharmacological of discharge tres improved.
