摘要：

The complete theory of adsorption of a Gaussian chain of finite length on the surface of a spherical adsorbent of an arbitary radius is developed on the basis of a continual (diffusion) model of the polymer chain. The influence of the dimensions of the adsorbent on the characteristics of the adsorptional transition is analysed. The partition function of the Gaussian chain near an adsorbing impermeable sphere is obtained. The diagram of states of the system in coordinates 'radius of the adsorbent-attraction energy' is constructed.
