| 摘要 |
<p>The present invention provides a composition wherein a homo-polymer or co-polymer of caprolactone has been produced by polymerising caprolactone, optionally with a co-monomer, in the presence of a polymerisation catalyst and an initiator, and the use of such a composition according for the manufacture of a polyurethane. <??>The present invention further provides a process for the production of a homo-polymer or a co-polymer of caprolactone comprising polymerising a composition comprising: (i) at least one caprolactone monomer and optionally a co-monomer; and (ii) a catalyst comprising (a) bismuth ethylhexanoate and ethylhexanoic acid, (b) bismuth ethylhexanoate and bismuth neodecanoate, or (c) zinc neodecanoate and zinc oxide.</p> |
