PC/PBT blends have excellent comprehensive properties and are widely used in the market. It's inevitable that transesterification reaction will take place in the melting process for this kind of blends, and this reaction has decisive effects on the blend properties, in this paper, the effects of resin ratio of PC to PBT, resin viscosity and processing technology on the transesterification reaction degree were studied. Considering that the reaction occurred at the phase interface of PC and PBT, with the combination of the phase morphology and crystallization behavior of PBT phase under different resin ratios, the correlation between phase morphology and transesterification degree was established. From the perspective of PBT phase, the lower its ratio is, the smaller its phase size is, the worse its crystallinity is, and the greater the transesterification degree, besides, the lower PBT resin viscosity, the higher the transesterification degree. Moreover, through the research on processing technology, the higher the extruder speed, the higher the transesterification degree. Those studies will provide direct guidance for further research on the influence factors of the transesterification degree and the actual processing of the corresponding products. © 2019 Kingfa SCI. & TECH.

Background: Experimental and epidemiological studies indicate an association between exposure to particulate matter (PM) air pollution and increased risk of type 2 diabetes. In view of the high and increasing prevalence of diabetes, we aimed to quantify the burden of type 2 diabetes attributable to PM_2·5 originating from ambient and household air pollution. Methods: We systematically compiled all relevant cohort and case-control studies assessing the effect of exposure to household and ambient fine particulate matter (PM_2·5) air pollution on type 2 diabetes incidence and mortality. We derived an exposure–response curve from the extracted relative risk estimates using the MR-BRT (meta-regression—Bayesian, regularised, trimmed) tool. The estimated curve was linked to ambient and household PM_2·5 exposures from the Global Burden of Diseases, Injuries, and Risk Factors Study 2019, and estimates of the attributable burden (population attributable fractions and rates per 100 000 population of deaths and disability-adjusted life-years) for 204 countries from 1990 to 2019 were calculated. We also assessed the role of changes in exposure, population size, age, and type 2 diabetes incidence in the observed trend in PM_2·5-attributable type 2 diabetes burden. All estimates are presented with 95% uncertainty intervals. Findings: In 2019, approximately a fifth of the global burden of type 2 diabetes was attributable to PM_2·5 exposure, with an estimated 3·78 (95% uncertainty interval 2·68–4·83) deaths per 100 000 population and 167 (117–223) disability-adjusted life-years (DALYs) per 100 000 population. Approximately 13·4% (9·49–17·5) of deaths and 13·6% (9·73–17·9) of DALYs due to type 2 diabetes were contributed by ambient PM2·5, and 6·50% (4·22–9·53) of deaths and 5·92% (3·81–8·64) of DALYs by household air pollution. High burdens, in terms of numbers as well as rates, were estimated in Asia, sub-Saharan Africa, and South Am
