| Abstract: | it is shown that a thiol u. v. stabilzer and a thiol heat stabilizer can be effectively bound to PVC during processing in the presence of an alk-yltin stabilizer. Thiol u.v.stabilizer interferes with the processing stability of PVC to a lesser extent than a conventional u. v. stabilizer ( 2 -hydroxy-4 octoxy benzophenone ) ( HOBP ) . The reason why DOTG has a good heat stabilization on PVC during processing. The heat stabilizers and u. v. stabilizers have a good synergistic action on PVC with their best molor ratio in the thermal-oxidative photo stabilization, however, the molar ratio relate to the stabilizer activity on PVC.The mechanism above is discussed and a new idea is offered which about theoretical quantity of .sta-bilizer used in PVC. |
