Polymeric compositions for sustained release of volatile materials |
| 摘要 |
A polymeric composition comprising a copolymer of ethylene with at least another monomer comprising at least a heteroatom, a tackifier, less than 10% of a compatible plasticizer or blend of plasticizers and a volatile material. The compositions are able to deliver effectively the volatile material incorporated for a long time and also have good adhesion properties on most substrates. |

1. A homogenous polymeric hot melt adhesive composition having a melting point of about 60° C. to about 80° C., comprising:
a) a copolymer of ethylene with vinyl acetate, a tackifier, which is a rosin that is solid at room temperature, and b) up to 10% by weight of the total weight of the composition of a compatible plasticizer or blend of plasticizers, c) a volatile material. |
