Copolymerization Of Methylacrylate And Acrylic Acid, N Y. Bozorov, V. O. Kudishkin
Scientific journal of the Fergana State University
Linear copolymers of methylacrylate and acrylic acid with different content of monomer units have been synthesized by classical radical copolymerization in dioxane solution and in the block. The composition of copolymers was determined. The relative activities of the monomers calculated by the methods of Fineman - Ross and Kelen -Tudos. It is shown that the activity of acrylic acid can vary depending on the medium in which copolymerization is carried out.

Defining The Antioxsidants Quantity In Certification Of The Chicken Meat, B. N. Sattarova, I. R. Asqarov, Sh. X. Abdulloev
Scientific journal of the Fergana State University
The article presents an analysis of the results obtained by chromatography-mass-spectrometric studies to determine the mass fractions of certain antioxidants in chicken meat, the excessive amount of which seriously threatens human health. The advantages of this method in the certification of meat products are substantiated. It has been established that the content of alpha-tocopherol in chicken meat imported from some foreign countries is several times higher than that produced in local poultry farms.
