POLYESTER BLENDS AND PROCESS FOR OBTAINING THESE |
摘要 |
The present invention relates generally to compositions of polyalkylene imine ("PAI"), particularly polyethylene imine ("PEI") and polyester polymer(s) (including copolymers and derivatives thereof); such compositions can be used in producing films or devices which are capable of scavenging unwanted aldehydes. More specifically, the preferred compositions of the present invention comprise a PAI substantially discontinuous phase and a polyester or copolyester substantially continuous phase in a weight ratio of PAI to polyester polymer of about 0.001-30:100 which optionally also includes a binding agent.
