Abstract
A process for manufacturing polymers containing a degradant component that increases the rate of polymer degradation. The process involves adding a degradant component to a fluid polymer immediately after the polymer is synthesized and while the polymer is still fluid to form a blend of the fluid polymer component and degradant component and mixing the blend of the fluid polymer component and degradant component to distribute the degradant component substantially homogeneously throughout the fluid polymer component.
Claims27
A method for manufacturing a polymer component containing a degradant component comprising the steps of:
- polymerizing one or more monomers to provide a fluid polymer component;
- and
- directly combining the fluid polymer component and degradant component to form a blend and to distribute the degradant component substantially homogeneously throughout the fluid polymer component.
A method for manufacturing a polymer article containing a degradant component comprising the steps of:
- polymerizing one or more monomers to provide a fluid polymer component;
- directly combining the fluid polymer component and degradant component to form a blend and to distribute the degradant component substantially homogeneously throughout the fluid polymer component;
- solidifying the blend of the fluid polymer component and degradant component;
- and
- forming the solidified blend into a polymeric article.
A method for manufacturing a polymer component containing a degradant component consisting essentially of the steps of:
- polymerizing one or more monomers to provide a fluid polymer;
- and
- directly combining the blend of the fluid polymer component and degradant component to form a blend and to distribute the degradant component substantially homogeneously throughout the fluid polymer component.
