AB  - We consider supersymmetric (SUSY) and non-SUSY models of chaotic inflation based on the phi(n) potential with 2 <= n <= 6. We show that the coexistence of a nonminimal coupling to gravity f(R) = 1 + c(R)phi(n/2) with a kinetic mixing of the form f(K) = c(K)f(R)(m) can accommodate inflationary observables favored by the BICEP2/Keck Array and Planck results for 0 <= m <= 4 and 2.5 x 10(-4) <= r(RK) = c(R)/c(K)(n/4) <= 1, where the upper limit is not imposed for n 2. Inflation can be attained for sub-Planckian inflaton values with the corresponding effective theories retaining the perturbative unitarity up to the Planck scale.
