Data confidence 85 high
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

A series of unsaturated polyester resin (UPRs) based on propylene glycol, diethylene glycol, Phthalic anhydride, maleic anhydride with different composition ratio were prepared by polycondensation reaction. Physico-mechanical properties including viscosity, hardness, acid number, gel and peak time are strongly dependent on the content of maleic anhydride in UPR. As increasing the content of maleic anhydride, physico-mechanical properties increased. The obtained UPR was stable for more than 6 months.
