Frontiers of Law in China-Selected Publications from Chinese Universities 2018年第2期13卷 260-290页

Nowadays, the complexity of financial products makes it difficult for retail clients to identify investment risks, and there is an increasing tendency for firms, stipulated by the maximum profits, to recommend or enter into unsuitable transactions to or for retail clients while providing services of investment advice and portfolio management, which causes great losses to a significant number of investors. So, in the contemporary society, the investor suitability rules through which retail clients can purchase suitable financial products are the indispensable legal basis of investor protection. Currently, the regulations concerning investor suitability management in China have several problems, including the chaotic legal system, low effectiveness level and defective contents, which may make it difficult for suitability to be applied in justice and managed effectively. Since the UK＇s investor suitability rules in the Conduct of Business Sourcebook that apply to retail clients whose contents include requirements of obtaining retail clients＇ information, requirements of information to be provided to retail clients and criteria of assessing suitability are clear and comprehensive, the authors believe that the UK＇s experiences can provide a great enlightenment for China to better investor suitability management rules, including integrating legal documents and optimizing effectiveness level, rationalizing application scope, adding criteria of assessing suitability and revising specific clauses.

Crosslinking reaction of LDPE resin in the presence of dicumyl peroxide （DCP） was studied by isothermal rheological measurements at different temperatures and non-isothermal differential scanning calorimetry （DSC） technique with different heating rates. The kinetic parameters of crosslinking reaction were calculated by both rheological and DSC measurements. The results reveal that with the increase of DCP contents, the apparent activation energy, Ea, ranges from about 140 kJ/mol to 170 kJ/mol and the order of crosslinking reaction, n, approaches unity. The influence of measurement frequency, on crosslinking reaction was also investigated. It can be found that n does not change with the increase of ωand Ea decreases slightly with the increase of ω
