An injection blow molding grade resin of improved clarity and processability is obtained by incorporating N,N¹-ethylene bisstearamide and an ethoxylated amine into a sodium benzoate nucleated propylene polymer.
solution lead to a mixture of o- and p-Bn-substituted phenols together with a substantial amount of phenol Bn ether. In CPME, and especially in toluene with 1–2 equivalents of ether or alcohol additives, ortho-selective alkylation is achieved. In the case of o,o,p-tri- and o,o-di-substituted phenols dearomatization occurs affording o-Bn-substituted alkyl cyclohexadienones with yields up to 92% with an o/p
