Polymers having improved processability |
摘要 |
Poly(lactones) are provided. The poly(lactones) are obtained by polymerization of a lactone with an initiator system comprising at least one polyfunctional initiator. The poly(lactones) have a shear viscosity at some temperature in the range of from 35 to 45° C. above the melting temperature of the poly(lactone) of at least 6 kPas at 0.1 s-1 shear rate and no greater than 3.5 kPas at 100 s-1 shear rate, and a shear viscosity activation energy of greater than 40 kJ/mol. Preferably, the poly(lactone) is poly(caprolactone). |
