Independent Claim
79 words
A PROCESS OF PREPARING A METAL ARTICLE HAVING A PROTECTIVE COATING THEREUPON COMPRISING THE STEPS OF COATING A SURFACE OF SAID METAL ARTICLE WITH A LIQUID POLYMER COMPOSITION COMPRISING AN ALKYL LITHIUM-CATALYZED POLYMER OF 1,3-BUTADIENE, AND CURING THE COATING TO BE A HARD, RESINOUS ADHERENT FILM, SAID CATALYST BEING SELECTED FROM THE GROUP CONSISTING OF (1) A COMPOSITION CONTAINING A PREDOMINATE PROPORTION OF AN ALKYL LITHIUM AND (2) CONSISTING ESSENTIALLY OF AN ALKYL LITHIUM AND A LITHIUM HALIDE ADMIXTURE.
Claim 2
Independent Claim
87 words
A METHOD FOR PREPARING AN UNSATURATED PREDOMINATELY TRANS-1,4-POLYBUTADIENE IN THE FORM OF A LIQUID POLYMER, COMPRISING POLYMERIZING A POLYMERIZABLE MONOMERIC UNSATURATED MATERIAL CONTAINING AT LEAST 90% 1,3BUTADIENE AT A TEMPERATURE BETWEEN ABOUT 20* C. AND 80* C., IN THE PRESENCE OF A CATALYST SELECTED FROM THE GROUP CONSISTING OF (1) A COMPOSITION CONSISTING ESSENTIALLY OF AN ALKYL LITHIUM AND (2) CONSISTING ESSENTIALLY OF AN ALKYL LITHIUM AND A LITHIUM HALIDE IN ADMIXTURE, IN THE PRESENCE OF A NON-POLAR HYDROCARBON SOLVENT, AND RECOVERING THE LIQUID, UNSATURATED, PREDOMINATELY TRANS-1,4POLUBUTADIENE.
