Abstract:
VINYLPYRIDINES ARE POLYMERIZED IN THE PRESENCE OF A POLYVINYL AROMATIC COMPOUND. THE POLYMERIZATION IS CARRIED OUT IN A REACTION MEDIUM COMPRISING METHANOL AND WATER. THE RESULTING POLYMER IS PARTICULARLY USEFUL AS A CATALYST SUPPORT.
Abstract:
The dye receptivity of polyolefins is improved by mixing 100 parts by weight of at least one polymer or copolymer of a 1olefin having two through eight carbon atoms per molecule with one to 20 parts by weight of a novel dye-receptive nonbasic polyamide modifier produced by polycondensing a diamine of which both amino groups are secondary with a hydrocarbon dicarboxylic acid.
Abstract:
In a polyesterification process, a suitable ester-forming sulfonate dyeability modifier is introduced into the reaction zone after the initial esterification or transesterification reaction is essentially complete.
Abstract:
A process for dyeing polyolefins in which there is incorporated in the polyolefin a polyester formed as the reaction product of 1,4-cyclohexanediol and a paraffinic dicarboxylic acid.
Abstract:
HYDROFORMYLATION REACTIONS ARE CARRED OUT IN THE PRESENCE OF A CATALYST COMPRISING A SOLID POLYMER HAVING ASSOCICATED THEREWITH A METAL OF THE GROUP COBALT,RHODIUM, RUTHEINIUM, PLATINUM AND PALLADIUM. THE POLYMER IS FORMED BY POLYMERIZING A PYRIDINE AND A STYRENE IN THE PRESENCE OF A POLYVINYLAROMATIC COMPOUND. THIS POLYMER CAN BY USED TO REMOVE CATALYST RESIDUES FROM HYDROFORMYLATION REACTION EFFLUENT STREAMS.
