THERMAL-BEHAVIOR OF P-ACRYLOYLOXY-TRI-N-BUTYLTIN BENZOATE ACRYLONITRILE COPOLYMERS

The copolymerization of p-acryloyloxy-tri-n-butyltin benzoate (ABTB) w ith acrylonitrile (AN) has been investigated in dimethylformamide (DMF ), using azobisisobutyronitrile (AIBN) as an initiator. The prepared h omopolymer of (ABTB), as well as the copolymers, were characterized by a variety of analytical, spectral, and thermal methods. Thermogravime try (TG) and differential thermal analysis (DTA) data showed a little improvement in the thermal behavior of the investigated copolymer. A m echanism for the initiation of ABTB units in the nitrile oligomerizati on in the copolymer was also proposed. (C) 1994 John Wiley & Sons, Inc .
