Abstract:
Graft copolymers are prepared in a two-stage process by first reacting, for example, 1,2-polybutadiene or an ethylene/propylene/alkylidene norbornene terpolymer, with a mixture of dinitrogen tetroxide and oxygen to form a nitrooxidized backbone polymer having incorporated therein nitro and peroxy nitrate functions which serve, in the second stage of the process, as sites for the subsequent graft polymerization of an acrylate monomer.
Abstract:
Amino ester products, useful as additives to lubricating oils, may be prepared by reaction of an alphanitroketone and a tertiary aminoalcohol.

Graft copolymers are prepared in a two-stage process by first reacting, for example, 1,2-polybutadiene or an ethylene/propylene/alkylidene norbornene terpolymer with dinitrogen tetroxide to form a nitrated backbone polymer having incorporated therein nitro and nitrite functions which serve, in the second stage of the process, as sites for the subsequent graft copolymerization of an acrylate monomer.
Abstract:
Vinyl monomers of the type exemplified by the alkyl methacrylates are homopolymerized in the presence of amine catalysts such as morpholine, piperidine, etc. to yield high molecular weight products.
