modifier in rigid PVC
Processing and compound properties
Blends of PVC and Baymod A 52 are prepared
and processed by the usual methods employed
for PVC. Processing aids are necessary, the
usual combinations of stabilisers and lubricants
being suitable.

After compounding in a high-speed mixer, the
dry blend can be processed straight away on
suitable equipment, e.g. twin-screw extruders.
For injection moulding and single-screw
extrusion, however, the processing of granules
has proved more suitable.
Rigid PVC modified with Baymod A 52 is
characterised by:
- very high toughness even with small
additions of modifier
- improved melting characteristics
- good surface finish
- good transparency and thermoforming of
film in comparison with standard MBS
modifiers.
Figures 1 and 2 show the mechanical
properties of laboratory compounds comprising
PVC and Baymod A 52.
