The polynomial $f(z)=f_0+f_1 z + \\cdots + f_d z^d$ is identified with the sequence $(f_0,f_1,\\ldots,f_d)$ of its coefficients. From the $L^4$ norm of a polynomial, one can easily calculate the autocorrelation merit factor of its associated sequence, and conversely. In this paper, we study the crosscorrelation properties of pairs of sequences associated to Rudin-Shapiro-like polynomials. We find an explicit formula for the crosscorrelation merit factor.
