Abstract
Disclosed herein is a method of making a melt-processable material comprises: processing a cross-linked polymeric foam to form a processed cross-linked polymeric foam material wherein the processed cross-linked polymeric foam material has an average particle size suitable for feeding to a melt processor, feeding the processed cross-linked polymeric foam material to the melt processor, and melt mixing a composition comprising the processed cross-linked polymeric foam material and a thermoplastic material wherein the processed cross-linked foam material has a domain size, under melt mixing conditions, less than or equal to the processing spaces of the melt processor.
Claims15
A method of making a melt-processable material comprising:
- processing a polymeric material comprising a thermoplastic material and a cross-linked polymeric foam to form a processed polymeric material comprising a processed thermoplastic material and a processed cross-linked polymeric foam wherein the processed polymeric material has an average particle size suitable for feeding to a melt processor and the processed cross-linked polymeric foam has an average particle size less than or equal to the average cell size of the cross-linked polymeric foam;
- feeding the processed polymeric material to the melt processor;
- and
- melt mixing a composition comprising the processed polymeric material in the melt processor at a temperature sufficient to melt the processed thermoplastic material wherein the processed cross-linked foam has a domain size, under melt mixing conditions, less than or equal to the processing spaces of the melt processor.
A method of making a melt-proces sable material comprising:
- processing a cross-linked polymeric foam to form a processed cross-linked polymeric foam material wherein the processed cross-linked polymeric foam material has an average particle size suitable for feeding to a melt processor and an average particle size less than or equal to the average cell size of the cross-linked polymeric foam;
- feeding the processed cross-linked polymeric foam to the melt processor;
- and
- melt mixing a composition comprising a thermoplastic material and the processed cross-linked polymeric foam material in the melt processor wherein the processed cross-linked foam material has a domain size, under melt mixing conditions, less than or equal to the processing spaces of the melt processor.
A melt-processable polymeric material comprising a thermoplastic matrix and dispersed cross-linked particles wherein the cross-linked particles are compressible.
