Abstract: The present invention relates to a method of preparing a polymer composition, the method comprising melt mixing an aliphatic condensation polymer with a cyclic ester of general formula (I) where X is an optionally substituted aliphatic hydrocarbon having 2 or more carbon atoms present in the cycle.

Abstract: The invention provides a process for increasing the melt flow index of a polyolefin, the process comprising using a melt mixing device to melt mix the polyolefin in contact with oxygen and a transition metal catalyst having a redox potential ranging from 0 to 2 volts, wherein oxygen is introduced to the melt mixing device, and wherein the transition metal catalyst in contact with the polyolefin forms at least part of a component of the melt mixing device.

Abstract: The present invention relates to masterbatches useful for modifying thermoplastic polyesters, in particular to masterbatches comprising dispersed polyol branching agent and/or chain coupling agents, such as for example dianhydrides. The invention also relates to a method for preparing the masterbatches, and to a method for modifying a polyester utilizing the masterbatches. Yet another aspect of the invention is the use of such a masterbatch composition for the modification of polyesters.

Abstract: A process for modifying a polypropylene (co)polymer wherein said process comprises melt mixing the polypropylene (co)polymer in the presence of an initiator wherein said initiator is selected from the group defined by formula (1), wherein R is selected from the group consisting of optionally substituted C1 to C18 acyl, optionally substituted C1 to C18 alkyl, aroyl defined by formula (2), and compounds of formula (3), wherein U, V, X, Y, Z, U?, V?, X?, Y? and Z? are independently selected from the group consisting hydrogen; halogen; C1-C18 alkyl; C1-C18 alkoxy, aryloxy, acyl, acyloxy, aryl, carboxy, alkoxycarbonyl, aryloxycarbonyl, trialkyl silyl, hydroxy, or a moiety of formula (4), and wherein T is alkylene.
