ABSTRACT:
An effective method for gelling certain organic liquids. The invention, in one embodiment, comprises forming a solution of the organic liquids and an amount of a triblock copolymer of relatively moderate molecular weight, having poly(4-vinylpyridene) end blocks and a small amount of a salt of a transition metal. In another embodiment, the invention comprises forming a solution of the organic liquids and an amount of a triblock copolymer of relatively moderate molecular weight, having poly(4-vinylpyridene) end blocks and a small amount of an acid. Such gelled liquids are useful as pipe line pigs, in automobile lacquers and in charcoal lighter fluids.
