We present a new class of 2d integrable models obtained as perturbations of minimal CFT with W-symmetry by fundamental weight primaries. These models are generalisations of well known (1, 2)-perturbed Virasoro minimal models. In the large p (number of minimal model) limit they coincide with scalar perturbations of WZW theories. The algebra of conserved charges is discussed in this limit. We prove that it is noncommutative and coincides with twisted affine algebra G represented in a space of asymptotic states. We conjecture that scattering in these models for generic p is described by the S-matrix of the q-deformed G-algebra with q being a root of unity.
