Explosives containing modified copolymers made from polyisobutylene and maleic anhydride as emulsifier

摘要

The emulsifying agent includes a copolymer containing a statistical or controlled sequence. The structural content is derived from maleic acid anhydride and from one or more olefins with more than 40 carbon atoms. The structural content derived from maleic acid anhydride is modified by reacting with alcohols, aminoalcohol, ammonia or amines. An Independent claim is included for a terpolymer containing monomers derived from an olefin with more than 40 carbon atoms, maleic acid anhydride and an alkylallypolyglycoether of formula R-(OCH2CH2)nOCH2CH=CH2, where n = 3 to 20 and R = C1 - C4 - alkyl.
