REACTIVE HETEROCHAIN OLIGOMERS BASED ON PROTON-CONTAINING ACRYLIC DERIVATIVES AND METHOD OF THEIR SYNTHESIS Russian patent published in 2003 - IPC

FIELD: organic chemistry, polymers, chemical technology. SUBSTANCE: invention describes reactive heterochain oligomers based on proton-containing acrylic derivatives of the general formula: CH₂= CH-C(O)O-(CH₂)_n-X- where X- means O-, -O-C(O)-N(Ph)-; n = 2-10; m = 2-15 and method of their synthesis by anionic polymerization of acrylic derivatives in the presence of initiating agent. Proton-containing acrylic derivatives are used as monomers and anionic polymerization is carried out in inert medium in the presence of initiating agents taken among the group: alkaline metals or their derivatives, mixture of α-oxide and tertiary amine in the mole ratio of components in the range 0.5-1.5, respectively and in the ratio of monomer and initiating agent is taken among the range (10-40): 1, respectively. Invention can be used in the field of synthesis of novel reactive oligomers, macromonomers designated for using as modifying additions, surface-active substances, dressing agents, compatibilizing agents in synthesis of polymeric mixtures, covers in electrical engineering, electronics and materials technology. EFFECT: improved method of synthesis and preparing. 4 cl, 1 tbl, 11 ex
