When the test substance was heated, the
first time there was no obvious change. Because of this, this test was
repeated at individual temperatures for seperate capillaries rather than
heating one capillary over the entire range (60 -300 degrees C). At
about 235 to 240 degrees C, it was observed that the sample collapsed
and chaged from white to colorless. The sample never liquified.
A study was conducted according to testing
Guideline OPPTS 830.7200 to determine the melting of zinc acrylate.
Under the testing conditions, the appearance of solid zinc acrylate
changed from white to colourless but did not liquify. Due to
homopolymerisation of the substance at 235 to 240 degrees centigrade, a
melting point could not be determined (Holyoke, 2003).
The melting point was determined
according to OPPTS Guideline 830.7200 (Holyoke, 2003).
No melting point but
homopolymerization at approx. 235 to 240 °C.
