  Hydrocarbon polymers such as ethylene copolymers may be reacted with unsaturated nitrogen-containing monomers or unsaturated carboxylic acids in the presence of a free radical catalyst such as a peroxide or azo free radical initiator and a chain stopping agent, e.g. a mercaptan to inhibit excessive cross-linking and branching. The copolymer grafted directly with the nitrogen-containing monomers may be utilized as an additive for oil and fuel compositions, particularly lubricating oil compositions as a V.I.-dispersant additive. The polymer reacted with carboxylic acid may be further reacted with amines, polyols, amino-alcohols, etc. to also form a V.L-dispersant additive.

  乙烯共聚物等烃类聚合物可与不饱和含氮单体或不饱和羧酸在过氧化物或偶氮自由基引发剂等自由基催化剂和硫醇等链阻断剂的存在下反应，以抑制过度交联和分支。 与含氮单体直接接枝的共聚物可用作油和燃料组合物的添加剂，特别是润滑油组合物的 V.I.分散添加剂。 与羧酸反应的聚合物可进一步与胺、多元醇、氨基醇等反应，以形成 V.L.分散添加剂。

  A compatibilizer for stabilizing polymer blends of olefin copolymer and polymethacrylate oil additives is prepared by graft polymerizing hydrocarbon backbone polymer with alkyl methacrylate monomer, in the presence of a free radical initiator, at a temperature of from 60°C to 175°C. The compatibilizer so formed comprises a graft copolymer-containing solution having a polymer solids content of from 40 to 60 percent, a viscosity of at least 8 x 10-3M2S-1 at 100°C, and a weight percent conversion of alkyl methacrylate monomer to polymer of no less than 90%.

  Olefin polymers are degraded in molecular weight in the presence of a free radical initiator under an inert blanket. The degradation preferably is carried out under high shearing stress and/or a high temperature in order to increase the degradation. The degradation may be separate from, overlap, or occur simultaneously with further derivatization of the polymer.

  烯烃聚合物在自由基引发剂的作用下，在惰性毯下进行分子量降解。降解最好在高剪切应力和/或高温下进行，以提高降解效果。降解可以与聚合物的进一步衍生化分开、重叠或同时进行。

  Hydrocarbon polymers such as ethylene copolymers may be reacted with unsaturated nitrogen-containing monomers or unsaturated carboxylic acids in a synthetic hydrocarbon lubricating oil in the presence of a free radical initiator such as a peroxide. The copolymer grafted directly with the nitrogen-containing monomers may be utilized as an additive for oil compositions, particularly lubricating oil compositions as a V.I.-dispersant additive. The polymer reacted with carboxylic acid may be further reacted with amines or aminoalcohols to also form a multifunctional V.I.-dispersant additive.

  Graft copolymers of nitrogenous monomer(s) on polymeric substrates, and their methods of preparation, are provided. The graft copolymers are produced by polymerizing monomers comprising one or more vinyl monomer into a polymeric substrate, and then grafting one or more nitrogenous monomer onto the polymeric substrate. Hybrid copolymers of a nitrogenous grafted copolymer with a nitrogenous random polymer, and methods for their preparation, are also provided. the hybrid copolymers can be prepared by first forming the nitrogenous graft copolymer and then copolymerizing additional constituent vinyl monomer(s) with residual nitrogenous monomer(s) to form the hybrid copolymer.
