For any pair $M,N$ of von Neumann algebras such that the algebraic tensorproduct $M\otimes N$ admits more than one $\mathrm{C}^*$-norm, the cardinal ofthe set of $\mathrm{C}^*$-norms is at least $ {2^{\aleph_0}}$. Moreover thereis a family with cardinality $ {2^{\aleph_0}}$ of injective tensor productfunctors for $\mathrm{C}^*$-algebras in Kirchberg's sense.  Let $\IB=\prod_n M_{n}$. We also show that, for any non-nuclear von Neumannalgebra $M\subset \IB(\ell_2)$, the set of $\mathrm{C}^*$-norms on $\IB \otimesM$ has cardinality equal to $2^{2^{\aleph_0}}$.

A continuum of $\mathrm{C}^*$-norms on $\IB(H)\otimes \IB(H)$ and related tensor products
