Cross-linked styrylphosphine resins

Abstract

Abstract NOVEL RESINS HAVING A CARBON-TO-CARBON BACKBONE, CROSS-LINKED WITH CARBON-TO-CARBON LINKAGES AND A PLURALITY OF PENDANT GROUPS OF THE STRUCTURE ((R-P(-R1)-(CH2)N-),R2-PHENYL)-CROSSLINKED POLYMER BACKBONE WHEREIN N IS AN INTEGER FROM 0 TO 3, R AND R1 ARE HYDROCARBON GROUPS OF FROM 1 TO 12 C ATOMS EACH, R2 IS H OR UP TO 4 ALKYL GROUPS OF 1 TO 4 C ATOMS EACH, ARE PREPARED BY COPOLYMERIZING A DIHYDROCARBYL VINYL AROMATIC PHOSPHINE WITH A POLYOLEFINICALLY UNSATURATED MONOMER OR BY COPOLYMERIZING SAID MONOMERS WITH ONE OR MORE MONOOLEFINICALLY UNSTURATED MONOMER WHICH IS COPOLYMERIZABLE WITH DIHYDROXARBYL VINYL AROMATIC PHOSPHINE AND/OR A VINYL AROMATIC COMPOUND. THE NOVEL CROSS-LINKED POLYMERS CAN ALSO BE PREPARED BY CONVERTING A CROSS-LINKED VINYL BROMINATED OR IODINATED AROMATIC HYDROCARBON POLYMER TO A LITHIUM DERIVATIVE AND THEN REACTING THE LATTER WITH A DIHYDROCARBYL HALO PHOSPHINE, OR REACTING THE LITHIUM DERIVATIVE WITH TRIMETHYLENE OXIDE, THEN HALOGEN, FOLLOWED BY LITHIUM DIHYDROCARBYL PHOSPHINE. THE NOVEL POLYMERS HAVE A UTILITY FOR CATALYZING REACTIONS IN WHICH MONOMERIC TRIHYDROCARBYL PHOSPHINES ACT AS CATALYSTS, NAMELY, THE DIMERIZATION OF ALPHA-BETA UNSATURATED NITRILES, CARBOXYLIC ACID ESTERS OR KETONES AND THE OLIGOMERIZATION OR POLYMERIZATION THEREOF UNDER CERTAIN CIRCUMSTANCES.
