Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
Solid-state polycondensation (SSP) is a competitive method of semicrystalline polymers synthesis to conventional melt polycondensation process. The molecular weight of polymers obtained according to this method is exceptionally high and the process can be carried out under milder conditions than those of the melt state. In this method the side reactions are suppressed, especially those leading to the polymer degradation. In this paper, which is a continuation of our previous publication, application of the SSP method to obtain high molecular weight poly(lactic acid) (PLA) and poly(glycolic acid) (PGA) - polymers of high importance for medicine and environmental protection - is presented and discussed. The two-phase model according to which polycondensation proceeds in the amorphous regions, and the apparatus usually used in this process are also described.
