The molecular weight distribution polyolefins rapid prototyping method in an industrial production conditions

The present invention relates to a rapid method for modeling an industrial production conditions at a molecular weight distribution of polyolefins, which affect a number of select molecular weight distribution of polymer product key operating variables as input variables, a plurality of parameters characterizing the molecular weight distribution as output variables, input between the data model and output variables, the core technology for the use of an olefin polymerization catalyst weighted overlap-parametric distribution function fitting the molecular weight distribution of products on each active site, established by the support vector machine algorithm parameters of the distribution function of the active site of the catalyst data model between the key during operation. The method of the present invention avoids the complex process of analysis of the mechanism, convenient on-site embodiment, high accuracy, especially for non-linear, high-dimensional data and the process is very rich in industrial applications; the present invention may be used to guide the actual or real-time monitoring of production, can improve the product quality, increase productivity, stable device operation, to bring greater economic benefits.
