In this paper, we investigate the solution of the generlized Smoluchovski equation related to w-polymer. The exact solution of this equation with kernel K(i1,i2,…,in)=const and K(i1,i2,…,in)=sumfrom i=1 to n(il) il are discussed for monodisperse condition. we obtain their explict expressions of the size distrbution C(t), respectively. In addition, we discuss their long term behaviors.
