Method of synthesizing a molecular sieve of MWW framework type

A method of synthesizing a molecular sieve of MWW framework type, the method comprising the steps of:

• a) preparing a synthesis mixture capable of 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, a source of poly(diallyldimethyl ammonium) cation (PDDA), optionally a source of a pentavalent element Z, optionally a source of hydroxide ions, and optionally seed crystals, the synthesis mixture having the following molar ratio composition:
• Si:X2=8 to less than 30,
• H2O:Si=5 to less than 50,
• M:Si=0.05 to 1.0,
• R:Si=0.05 to 1.0,
• wherein the source of PDDA is added in an amount of from 0.01 to less than 1.0 wt % based on the weight of synthesis mixture;
• b) heating said synthesis mixture under crystallization conditions for a time sufficient to form crystals of said molecular sieve of MWW framework type, said crystallization conditions including a temperature of from 80° C. to 225° C.;
• and
• c) recovering said crystals of the molecular sieve of MWW framework type from the synthesis mixture.
