英文摘要	The effect of radiation on high-charge-density cationic polymer, polydiallyl-dimethyl ammonium chloride (polyDADMAC), in dilute aqueous solution was investigated. The irradiated samples were characterized in terms of reduced viscosity and electric conductivity. The crosslinking reaction of polyDADMAC chains occurs preferentially in the irradiated samples at a concentration of polyDADMAC higher than 1.3 g/100 mL that was induced indirectly by the OH radicals, one of the radiolysis products of water. In more dilute samples (less than 0.8 g/100 mL) the chain scission of macro radicals appears to be the main reaction. N2O atmosphere enhances the crosslinking due to the extra OH radicals produced by reaction between N2O and e(aq)(-), another radiolysis products of water. Methanol and some mineral salts such as KCl, KBr inhibit the crosslinking to a certain extent. The mechanism of sensitization and inhibition is discussed in detail.; Polymer Science; SCI(E); EI; 中国科学引文数据库(CSCD); 1; ARTICLE; 4; 459-464; 21
