  • Patent number: 4091007
    Abstract: An improved method for preparing a crystalline aluminosilicate zeolite having uniform pores and greater than 40 percent crystallinity which comprises forming a critical reaction mixture containing a source of at least two cations, silica, alumina and water, wherein at least about 70 weight percent of the alumina is provided to the reaction mixture by an alumina-containing clay being added thereto, and maintaining the reaction mixture at a temperature and pressure for a time necessary to crystallize the crystalline aluminosilicate from the reaction mixture. It is desirable to preform said reaction mixture into discrete particles such as pellets or extrudates which retain their shape and acquire substantial strength in the crystallization process.

These copolymers have molecular weights in the range of from about 1,000 to 500,000. The copolymers are particularly useful in lubricating oils, greases and fuels, especially cross-graded lubricants, crude oils, diesel oils, gasoline and fuel oils.
