    Abstract: A band-shaped high-temperature superconductor (HTSL) with high critical current density can be produced economically in a wet-chemical process. In the process, a first precursor solution is applied to a carrier, dried, and annealed. Additional precursor solutions may then be applied, with the first precursor solution contain little or no pinning centers, and any subsequent precursor solutions contains a higher concentration of pinning centers than the first precursor solutions.

    Abstract: 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.

    Abstract: 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.
