摘要： The invention relates to a process for grafting hydrolysable silane groups to a polyolefin in which ethylene units, if present, form less than 50% by weight of the total polyolefin. The polyolefin is reacted with an unsaturated silane, having at least one hydrolysable group bonded to Si, or a hydrolysate thereof, in the presence of means capable of generating free radical sites in the polyolefin. The unsaturated silane has the formula R″—CH═CH—Z (I) or R″—C≡C—Z (II) in which Z represents an electron-withdrawing moiety substituted by a —SiRaR′(3-a) group wherein R represents a hydrolysable group; R′ represents a hydrocarbyl group having 1 to 6 carbon atoms; a has a value in the range 1 to 3 inclusive; and R″ represents hydrogen or a group having an electron withdrawing or any other activation effect with respect to the —CH═CH— or —C≡C— bond. The use of an unsaturated silane of the formula R″—CH═CH—Z (I) or R″—C≡C—Z (II) in carrying out the grafting reaction on the polyolefin may give enhanced grafting yield compared to grafting with an olefinically unsaturated silane such as vinyltrimethoxysilane not containing an electron withdrawing moiety Z. The invention permits to provide a silane-modified polyolefin having a high grafting efficiency while limiting/preventing polymer degradation by chain scission. The silane-modified polyolefin can be further reacted with a polar surface, a filler or a polar polymer or reacted on itself to crosslink the polyolefin and obtain enhanced physical properties of the composites made thereof.

摘要： This invention relates to the modification of elastomers by reaction with unsaturated silanes, to the modified elastomers produced and to articles produced by shaping and curing modified elastomer compositions. In a process according to the present, the silane has the formula: R″—CH═CH—C(O)X—Y—SiRaR′(3-a) (I) or R″—C≡C—C(O)X—Y—SiRaR′(3-a) (II) in which R represents a hydrolysable group; R′ represents a hydrocarbyl group having 1 to 6 carbon atoms; a has a value in the range 1 to 3 inclusive; Y represents a divalent organic spacer linkage comprising at least one carbon atom separating the linkage —C(O)X— from the Si atom, X is S or O; and R″ represents hydrogen or a group having an electron withdrawing effect with respect to the —CH═CH— or —C═C— bond; and the silane is reacted with the diene elastomer in the absence of any free radical initiator. This is advantageous because free radical initiators such as peroxides tend to degrade diene elastomers. In addition, safe handling and mixing of peroxides can be difficult for rubber compounders. The grafted diene elastomer produced has improved adhesion to substrates, for example reinforcing cords and fabrics used as reinforcement in rubber articles such as tyres.

The invention permits to provide a silane-modified polyolefin having a high grafting efficiency while limiting/preventing polymer degradation by chain scission. The silane-modified polyolefin can be further reacted with a polar surface, a filler or a polar polymer or reacted on itself to crosslink the polyolefin and obtain enhanced physical properties of the composites made thereof.
摘要翻译：本发明涉及将可水解硅烷基接枝到聚烯烃上的方法，包括使聚烯烃与不饱和硅烷反应，所述不饱和硅烷含有烯烃-C = C-键或炔属-C = C-键并且具有至少一个可水解基团键合到 Si或其水解产物，在能够在聚合物中产生自由基位点的手段存在下进行。所述硅烷含有芳环或其它烯属双键或炔属不饱和键，所述芳环或所述其它烯属双键或炔属不饱和键与所述硅烷的烯烃-C = C-或炔属-C = C-不饱和键结合。相对于烯烃-C = C-或炔属-C = C-键，不饱和硅烷还可含有吸电子部分。本发明允许提供具有高接枝效率的硅烷改性聚烯烃，同时通过链断裂限制/防止聚合物降解。硅烷改性的聚烯烃可以进一步与极性表面，填料或极性聚合物反应，或者自身反应以使聚烯烃交联并获得由其制成的复合材料的增强的物理性能。
