ABSTRACT:
The present invention discloses a method of dispersing cyclodextrins into a base polymer. The method of the invention comprises reacting grafted microfine polymer powder with a cyclodextrin to form a cyclodextrin-attached grafted polymer, and mixing the cyclodextrin-attached grafted polymer and the base polymer for a sufficient time that the cyclodextrin-attached grafted polymer is dispersed within the base polymer. The present invention also provides several cyclodextrin-inclusion complex products formed by the method of the invention. This products include an antimicrobial polymer blend, a fragrant polymer blend, and a dyed polymer blend.
