Abstract:
A propene terpolymer consisting of from 80 to 99.5 mol % of structural units derived from propene, from 0.1 to 15 mol % of structural units derived from ethene or a C4-C6-1-olefin (I) and from 0.1 to 15 mol % of structural units derived from a further C4-C12-1-olefin (II) which is different from the C4-C6-1-olefin (I), which propene terpolymer has a proportion of regioregular â€²1-2â€²-inserted propene units corresponding to the formula (1) [â€²&it;1-2â€²][â€²&it;1-2â€²]+[â€²&it;2-1â€²]+[â€²&it;1-3â€²](1)of more than 0.99, has a melting point (TM), determined from the DSC peak maximum, of less than 135Â° C. and a weight average molecular weight (MW) of more than 80,000 g/mol and has a xylene-soluble proportion (XS) in % by weight of the propene terpolymer which obeys the following inequality (2)XS&lE;1411.21 exp(âˆ’0.0591 TM[Â° C.])âˆ’0.05â€ƒâ€ƒ(2).
