| abstract |
Polymer compositions suitable for modeling are provided as plastisols with a high content of volatile substances, such as bactericidal, aromatizing, and/or flavoring volatiles. Such plastisols are provided by mixing a lyophilic polyamide or lyophilic complex polyester with a plasticizer of moderate to low polarity that includes a bactericidal, aromatizing, and/or flavoring components, such as an essential oil. After mixing, additives such as fillers, pigments, and gelling agents are added. A solid plastic is producing by heating the formed plastisol to a gelation temperature and then heating to a solution temperature to generate a solid plastic with enduring bactericidal activity, scent, and/or flavor. |
