Polynomials with real coefficients are considered, Hurwitz polynomials and the Hadamard power of polynomials are defined. Some known results are reproduced for a better understanding. The main results are: 1. The \(p\)th Hadamard power of a Hurwitz polynomial is a Hurwitz polynomial. 2. The Hadamard powers of so-called interlacing polynomials remain interlacing.
