Abstract: Anionic polymerization initiators useful in the preparation of polymers having a protected amine functional group. The amine functionality is part of a heterocyclic radical and includes a protecting group.

Abstract: Anionic polymerization initiators useful in the preparation of polymers having a protected amine functional group. The amine functionality includes a first protecting group, which can be aralkyl, methyl, allyl or tertiary alkyl group. The other of the amine protecting groups can be the same as the first protecting group. Alternatively, the second protecting group can be different from the first protecting group, in which case it is selected to have differential stability to agents used to remove the aralkyl, methyl, allyl or tertiary alkyl protecting group.

Abstract: For a component produced using integrated technology for providing integrated circuits with at least one programmable matrix shaped connecting field formed on a substrate with line and column conductors which can be connected in the area of at least one part of their intersecting points by coupling elements, two activatable or two deactivatable coupling elements (42,44) with a direction of activity at an angle of 90.degree. to one another are assigned to each of at least one part of the intersection points within the connecting field.

Abstract: A logic array module, produced by integrated techniques for forming integrated circuits, encompasses a substrate on which are designed at least one linking field and outside of it active elements which serve for the input and output of signals and for expanding the scope of the linking field, and it is constructed of tracks (48, 56; 46, 54), arranged in the shape of columns and lines, which can be intercoupled on their crossing points (intersections) by activatable or deactivatable coupling elements (50, 58) that, depending on the status (state of connection) of a track, influence the status of a track that crosses the former so that logic linkages can be realized on the crossing track.

Abstract: An integrated circuit component, particularly a programmable logic array (PLA), includes at least one logic AND-array and a logic OR-array connected thereto. Some of the input lines of the PLA are sued to control the selection of output signals of the OR-array via a multiplexer thereby reducing the complexity and necessary programming of the PLA without a loss of flexibility.

Abstract: A programmable logic array chip is provided with an auxiliary grid pattern of conductive paths. Connecting elements can be selectively activated to connect certain ones of the auxiliary paths to the normal grid pattern paths which are connected to functional elements. In such manner, it is possible to provide a logic array chip that has increased flexibility in terms of user programmable functions.
