A catalytic system with an increased activity for the (co)polymerization of alpha-olefins comprises a catalyst of the metallocene type, which is capable of polymerizing olefins without aluminoxane, and a weak coordinating compound, which, when used in a polymerization process, enables a higher productivity than an analogous process carried out with the metallocene type catalyst per se.

An Antibiotic Complex AB-023 and its components: Antibiotic AB-023a and Abiotic AB-023b are disclosed, which are obtained by the controlled aerobic culture of Streptomyces sp. NCIMB 40212 in an aqueous nutrient culture substrate. Antibiotic AB-023 displays a biological activity against pathogen fungi which attack agricultural crops and man.
