Abstract:
Compounds of the structure WHEREIN Ar is a mono- or polynuclear aromatic radical, and R and R'' are C1 to C20 hydrocarbon radicals. These compounds are useful as initiators or activators in the anionic polymerization of lactam monomers.
Abstract:
Certain N-substituted nylon-1 compounds are utilized as nontoxic polymerization initiators or activators with alkaline catalyst in the anionic polymerization of lactam monomer so as to provide for a rapid polymerization process wherein polymerization conditions are more readily controlled due to the gradual development of exotherms.

Abstract:
Reversibly cross-linked, thermoplastic, normally solid polymer salt compositions have been prepared by copolymerizing a prepolymer of a carboxyl containing polyolefin, having 2 to 50 mole percent carboxylic acid groups, and about 10 to 100 mole percent of its carboxyl groups neutralized with an amino vinyl monomer such as an alkylaminoalkyl acrylate, an alkylaminoalkyl methacrylate, or an amino substituted styrene with a vinyl monomer such as an alkyl acrylate, an alkyl methacrylate, acrylamide, methacrylamide, styrene, alkyl substituted styrenes, vinyl chloride, vinyl esters containing from three to 20 carbon atoms or vinyl alkyl ethers containing from three to 20 carbon atoms. These polymer salt compositions are particularly useful in that they exhibit a high degree of adhesion to plasticized vinyl chloride resins, unlike most other commonly known adhesives, as well as other substrates.
Abstract:
POLYTHIOLACTONES ARE UTILIZED AS POLYMERIZATION INITIATORS OR ACTIVATORS WITH ALKALINE CATALYSTS IN THE ANIONIC POLYMERIZATION OF LACTAM MONOMERS SO AS TO PROVIDE FOR A RAPID POLYMERIZATION PROCESS. THE POLYMERS THUS OBTAINED HAVE GOOD PHYSICAL PROPERTIES AND GOOD COLOR.
