Legitimacy Crisis

Fairbrother's Toward Critical Patriotism is a timely publication in the “Hong Kong Culture and Society” series: political squabbles and conflicts over the idea of patriotism in the context of the national security legislation in Hong Kong are inflamed following the spectacular mass demonstration by 500,000 people on 1 July 2003. As the author points out, patriotism and nationalism are relatively recent historical phenomena in China. In mainland China, Marxist-Leninism became the guiding ideology after 1949. Yet, from the early 1980s, in the face of a legitimacy crisis, the leadership shifted toward patriotism as a unifying and justificatory ideology while professing ultimate objectives in line with Marxist principles. In Hong Kong, civic education had been de-emphasized under the ideology of de-politicization by the colonial government until the handover in the 1990s. The book rejects the typical characterization of Hong Kong students as simply having a weak sense of patriotism and nationalism, and of mainland students as patriotic dupes under the state and presents a more nuanced analysis.

Aromatic Dicarboxylic Acids

A new aromatic diamine, 10,10-bis[4-(4-aminophenoxy)phenyl]-9(10 H)-anthrone (BAPA) has been synthesized from anthrone via three-step procedure. Direct phosphorylation polycondensation of BAPA with various aromatic dicarboxylic acids produced a series of cardo poly(ether amide)s with inherent viscosities of 0.97–1.29 dL g−1. All the polymers were readily soluble in polar solvents such as N-methyl-2-pyrrolidone, N, N-dimethylacetamide (DMAc), and pyridine at room temperature, and afforded transparent, strong, and flexible films upon casting from DMAc solvent. The resulting poly(ether amide)s had glass transition temperatures of 254–316°C, 10% weight loss temperatures of 495–524°C, and char yields of 55–70% at 800°C in nitrogen. These polymers were amorphous and their films exhibited tensile strengths of 81.6–104.7 MPa, tensile moduli of 1.8–2.4 GPa, and elongations at break of 8–15%.
