Modified polymers having controlled transmission rates

摘要: The present invention includes processes and resulting structures for producing a modified polymer having channels. channels act as controlled transmission passages through the polymer. A (25) is caused to assume molten state, typically by applying heat melting channeling agent (35) blended then reacted into so that it distributed within In one embodiment, an absorbtion additive (30) product forms (45) in which desired compound communicable entrained product. solidified may be used form shaped article such plug type inserts (55) liners (70) closed containers (60), or formed film, sheet (75), bead, pellet.
