The tensile mechanical properties and fracture toughness of a Bisphenol‐A type difunctional epoxy resin, cured with different amounts of metaphenylene diamine, using two cure cycles, were determined over a range of temperature. The tensile modulus in the glassy state was seen to be predominantly related to intermolecular packing, while in the rubbery state crosslink density was the important factor. Yielding appeared to be due to an increase in free volume as a result of dilatation during the tensile test and was related to a critical shear stress. The large strain properties like tensile strength, elongation‐to‐break, and toughness showed a more complex dependence on chemical structure, molecular architecture, intermolecular packing, and crosslink density. The roles played by the relaxation processes in determining mechanical properties are highlighted.

Inderstanding the dynamics of policy distribution requires an appreciation of federal grant programs that have achieved a prominent place in nearly all areas of domestic policy. The theoretical literature on distributive politics, however, focuses almost exclusively on a centralized, top-down view of policy distribution. By examining the role of presidents, legislators, and bureaucrats, scholars have ignored participants who have become key actors in the distribution of federal expenditures-the recipient jurisdictions. This analysis of the allocation patterns under six federal programs shows that local governments exert important influences on the distribution of federal grants and that the distributional patterns and their determinants vary over time.The analysis also points out the importance of disaggregation by focusing on programs and recipient jurisdictions, as opposed to total federal expenditures and regions, states, or congressional districts.
