Abstract
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.
Claims8
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.
A polymeric composition according to any preceding claim wherein the copolymer is from 5% to 75% by weight of the polymeric composition, the tackifier is from 10% to 60% by weight of the copolymer and the volatile material is more than 10% of the total weight of the composition.
