PLASTICIZER

A plasticizer having excellent weatherability. The plasticizer comprises an acrylic polymer obtained through polymerization at a temperature as high as 180 to 350 DEG C. The acrylic polymer preferably has a weight-average molecular weight of 500 to 10,000 and a viscosity at 25 DEG C of 100,000 cP or...

More Information
Summary:A plasticizer having excellent weatherability. The plasticizer comprises an acrylic polymer obtained through polymerization at a temperature as high as 180 to 350 DEG C. The acrylic polymer preferably has a weight-average molecular weight of 500 to 10,000 and a viscosity at 25 DEG C of 100,000 cP or lower. This plasticizer preferably has a plasticizing efficiency of 30 to 150. For use in the plasticization of vinyl chloride resins, the plasticizer preferably comprises the acrylic polymer having a Q value of 11.5 to 16. For the plasticization of ABS resins, the plasticizer preferably comprises the acrylic polymer having a Q value of 13.5 to 16. L'invention concerne un plastifiant présentant une excellente altérabilité. Le plastifiant comprend un polymère acrylique obtenu par polymérisation à une température élevée comprise entre 180 et 350 DEG C. Le polymère acrylique possède, de préférence, un poids moléculaire moyen compris entre 500 et 10000 et une viscosité à 25 DEG C d'au plus 100000 cP. Le plastifiant comprend, de préférence, une efficacité de plastification comprise entre 30 et 150. Lorsque ce plastifiant est utilisé dans la plastification de résine de chlorure de vinyle, il comprend, de préférence, le polymère acrylique ayant une valeur Q comprise entre 11, 5 et 16. Pour la plastification de résines ABS, le plastifiant comprend, de préférence, le polymère acrylique ayant une valeur Q comprise entre 13,5 et 16.
