Abstract:
A process comprising the steps of:(a) adding a substantially organic molten component with CSP value of at least 8 to a molten thermoplastic polymer and mixing to substantially uniformly disperse said molten component in said molten thermoplastic polymer and form a heterogeneous blend wherein (i) the melt viscosity of said molten component is substantially less than the melt viscosity of said molten thermoplastic polymer; and (ii) the amount of said molten component in said molten thermoplastic polymer is up to about ten percent by weight based on said heterogeneous blend; and (b) melt processing said heterogeneous blend wherein said molten component preferentially locates near the surface of said molten thermoplastic polymer and substantially no chemical reaction occurs between said molten component and said molten thermoplastic polymer.
