We study some properties of subclasses of of the Caratheodory class of functions, related to conic sections, and denoted by P(pk). Coefficients bounds, estimates of some functionals are given. Keywords: the Caratheodory class, extremal problems, Fekete-Szego-Goluzin functional AMS Subject classification: 34A25, 30C35, 33E05, 30C45.
