Studies On The Relationship Between Processing Parameters, Construction And Mechanical Properties Of Acrylic Resin Modifying UPVC

In this paper, some works have been done in the relationship between mechanical properties, processing parameters and micromorphology of Acrylic resin (ACR) particle with core-shell construction modifying UPVC.Though the test of mechanical properties of PVC/ACR compound, it can be known that the impact strength of the compound modified with ACR in 6-8 phr is much higher than with CPE (36% Cl) in 10 phr.The construction of ACR plays an important role in ACR toughening UPVC. In the core monomers must be polymerized totally and cross-linked. The content of cross-link agent should be controlled in 1 ~ 1.5%. The rubber core in ACR plays a critical role in toughening UPVC, too. The result of the experiment shows that the content of the rubber core in 70% should be enough. The particle size of ACR should be controlled in0.5~2um.
