Abstract
In some instances, adhesives may include a cellulose ester and a plasticizer in an amount of about 15% or greater by weight of the adhesive, wherein the plasticizer comprises a nonionic surfactant. In some instances, adhesives may include a cellulose ester and a mixture of two or more plasticizers in an amount of about 15% or greater by weight of the adhesive, wherein a melt flow index of the adhesive melt is greater than comparable adhesive melts that comprise the cellulose ester and only one of the plasticizers at the same amount.
Claims20
An adhesive comprising:
- a cellulose ester;
- and
- a plasticizer in an amount of about 15% or greater by weight of the adhesive, wherein the plasticizer comprises a nonionic surfactant.
An adhesive comprising:
- a cellulose ester;
- and
- a mixture of two or more plasticizers in an amount of about 15% or greater by weight of the adhesive;
- wherein a melt flow index of the adhesive is greater than comparable adhesives that comprise the cellulose ester and only one of the plasticizers at the same amount.
A method comprising:
- producing an adhesive melt comprising a cellulose ester and a plasticizer at about 15% or greater by weight of the adhesive to yield an adhesive melt, wherein the plasticizer comprises a nonionic surfactant;
- and
- applying the adhesive melt to a substrate.
A method comprising:
- producing an adhesive melt comprising a cellulose ester and a mixture of two or more plasticizers in an amount of about 15% or greater by weight of the adhesive, wherein a melt flow index of the adhesive melt is greater than comparable adhesive melts that comprise the cellulose ester and only one of the plasticizers at the same amount;
- and
- applying the adhesive melt to a substrate.
