Copolymers of Butyl Acrylate with Vinyl Alkyl Ethers as Thickening Additives to Oils

摘要

The possibility of preparing copolymers of butyl acrylate with vinyl butyl and vinyl isobutyl ethers with various ratios of monomeric units by radical polymerization was examined.Macromolecular compounds are widely used as depressor and thickening additives to oils1,2.Well-known additives based on polyalkyl methacryl-ates often exhibit thickening and depressor properties simultaneously3-6.However,the use of alkyl acrylates,in particular,polybutyl acrylate,for this purpose is restricted by their limited solubility in oils7.
