Abstract:
A method for forming a polyalkylene-grafted centipede polymer comprisinga) reacting, under substantially dry conditions,1) from about 50 to about 99 weight percent of a copolymer of a maleimide and an olefin having the formula R.sup.1 R.sup.2 C.dbd.CH.sub.2 wherein R.sup.1 and R.sup.2 independently are unsubstituted or substituted C.sub.1 -C.sub.20 alkyl groups,2) from about 1 to about 50 weight percent of a maleated polyalkylene, and3) from about 0.1 to about 10 weight percent of a diamine,so as to form said polyalkylene-grafted centipede polymer; andb) optionally, mixing said polyalkylene-grafted centipede polymer with a sufficient amount of an extender so as to form a gel.
