Process for improving the properties of polymers

This invention relates to a process of forming a polyamide composition having increased crystallization rate which comprises the steps of reducing the oligomeric polyamide content of said composition to less than 8% by weight of the composition, preferably with prior melt shearing, use of 1-2% nucle...

More Information
Summary:This invention relates to a process of forming a polyamide composition having increased crystallization rate which comprises the steps of reducing the oligomeric polyamide content of said composition to less than 8% by weight of the composition, preferably with prior melt shearing, use of 1-2% nucleating filler e.g. talc and a mold release agent.
