Novel method of producing two-component and multi-component copolymers containing conjugated diene compounds and conjugated polar vinyl monomers using photo polymerization
Abstract 1. A METHOD OF PRODUCING ALTERNATING COPOLYMERS OF CONJUGATED DIENE AND CONJUGATED POLAR VINYL MONOMERS, WHEREIN THE MOLAR RATIO OF THE CONJUGATED DIENE UNITS TO THE CONJUATED POLAR VINYL MONOMER UNITS IS ALWAYS 1:1, COMPRISING IRRADIATING A LIGHT HAVING A WAVE LENGTH OF 2,000-6,000 ANGSTROMS TO A POLYMERIZATION REACTION SYSTEM COMPOSED OF AT LEAST ONE CONJUGATED DIENE HAVING THE GENERAL FORMULA R1-CH=C(-R3)-C(-R2)=CH-R4 WHEREIN R1, R2, R3 AND R4 REPRESENT HYDROGEN ATOMS, HYDROCARBON RADICALS HAVING 1 TO 5 CARBON ATOMS OR HYDROCARBON RADICALS HAVING SUBSTITUENTS OF THESE RADICALS, AND AT LEAST ONE CONJUGATED POLAR VINYL MONOMER HAVING THE GENERAL FORMULA CH2=C(-Z)-R7 WHEREIN R7 REPRESENTS A HYDROGEN ATOM, A HYDROCARBON RADICAL HAVING 1 TO 10 CARBON ATOMS OR A HYDROCARBON RADICAL HAVING SUBSTITUENTS OF THE RADICAL, Z REPRESENTS A NITRILE GROUP OR AN ESTER GROUP HAVING THE GENERAL FORMULA -COO-R8 WHEREIN R8 REPRESENTS A HYDROCARBON RADICAL HAVING 1 TO 10 CARBON ATOMS, THE MOLAR RATIO OF SAID CONJUGATED DIENE TO SAID POLAR VINYL MONOMER BEING 1-20 TO 20:1, AT A TEMPERATURE OF -100+100*C., IN LIQUID STATE, IN THE PRESENCE OF AT LEAST ONE CATALYTIC COMPONENT SELECTED FROM THE GROUP CONSISTING OF METAL HALIDES HAVING THE GENERAL FORMULAE ZNX2 AND ALX3 WHEREIN X REPRESENTS A HALOGEN ATOM, THE AMOUNT OF SAID CATALYTIC COMPONENT BEING IN THE RANGE OF 1/10**6 TO 1/2 MOLE PER 1 MOLE OF THE TOTAL FED MONOMER.
A METHOD OF PRODUCING ALTERNATING COPOLYMERS OF CONJUGATED DIENE AND CONJUGATED POLAR VINYL MONOMERS, WHEREIN THE MOLAR RATIO OF THE CONJUGATED DIENE UNITS TO THE CONJUATED POLAR VINYL MONOMER UNITS IS ALWAYS 1:1, COMPRISING IRRADIATING A LIGHT HAVING A WAVE LENGTH OF 2,000-6,000 ANGSTROMS TO A POLYMERIZATION REACTION SYSTEM COMPOSED OF AT LEAST ONE CONJUGATED DIENE HAVING THE GENERAL FORMULA R1-CH=C(-R3)-C(-R2)=CH-R4 WHEREIN R1, R2, R3 AND R4 REPRESENT HYDROGEN ATOMS, HYDROCARBON RADICALS HAVING 1 TO 5 CARBON ATOMS OR HYDROCARBON RADICALS HAVING SUBSTITUENTS OF THESE RADICALS, AND AT LEAST ONE CONJUGATED POLAR VINYL MONOMER HAVING THE GENERAL FORMULA CH2=C(-Z)-R7 WHEREIN R7 REPRESENTS A HYDROGEN ATOM, A HYDROCARBON RADICAL HAVING 1 TO 10 CARBON ATOMS OR A HYDROCARBON RADICAL HAVING SUBSTITUENTS OF THE RADICAL, Z REPRESENTS A NITRILE GROUP OR AN ESTER GROUP HAVING THE GENERAL FORMULA -COO-R8 WHEREIN R8 REPRESENTS A HYDROCARBON RADICAL HAVING 1 TO 10 CARBON ATOMS, THE MOLAR RATIO OF SAID CONJUGATED DIENE TO SAID POLAR VINYL MONOMER BEING 1-20 TO 20:1, AT A TEMPERATURE OF -100+100*C., IN LIQUID STATE, IN THE PRESENCE OF AT LEAST ONE CATALYTIC COMPONENT SELECTED FROM THE GROUP CONSISTING OF METAL HALIDES HAVING THE GENERAL FORMULAE
