Abstract
Disclosed is a method of synthesizing a molecular sieve of MWW framework type, and molecular sieves so synthesized. The method comprises preparing a synthesis mixture for forming a molecular sieve of MWW framework type, said synthesis mixture comprising water, a silicon source, a source of a trivalent element X, a structure directing agent R, a source of alkali or alkaline earth metal cation M, and a source of poly(diallyldimethyl ammonium) cation (PDDA).
