The first poly I worked with was Polystar and Dynocraft from Snauwaert. Was around 1981/82. Available in 1.2 and 1.3. Played ok (1.2), lost tension fairly quick and had not that much grip on the ball, slice was harder.
Was a "hard string" which sort of drilled itself into the wooden rackets quickly.
The 1.2 played ok but did not last to long on red clay, for sure in mid or oversize rackets.
