Abstract ： In the process of polyester synthesis, nano-barium sulfate is added to prepare a master batch of polyester
blocking agent for film. Investigate the influence of nano-barium sulfate on the polymerization reaction, analyze the
performance of the anti-blocking agent masterbatch containing nano-barium sulfate, use a small-scale extrusion cast
ing machine and a film stretcher to test the barium sulfate anti-blocking agent master batch for casting and filming,
investigate the film-forming performance, and analyze the performance o
