A novel hot-melt adhesive and a preparation method thereof are disclosed, and in particular a hot-melt adhesive for bonding aluminum, stainless steel or other metal materials and PVC plastics is disclosed. The specific nylon-type copolyamide is firstly prepared by designing specific raw materials and percentage thereof, and in combination with favorable bonding properties of the nylon-type copolyamide for metals and favorable bonding characteristics of the perchloroethylene resin for PVC, a double screw extruder is utilized to perform sufficient melt blending on the nylon-type copolyamide and the perchloroethylene resin under the synergistic actions of related aids, so that the obtained novel hot-melt adhesive has favorable bonding properties for both metals and PVC.

There is disclosed a phthalate-free, epoxidized plasticizer composition comprising a blend of: a) one or more fatty acid esters having less than 10% saturates; and b) one or more bio-based oil having an oxirane value of at least 5.0%. There is also disclosed a method of making a phthalate-free, epoxidized plasticizer composition comprising forming a blend of the fatty acid esters bio-based oils, wherein the one or more fatty acid esters and the bio-based oils are epoxidized either prior to forming the blend or in a single epoxidation step after the blend is formed. Plasticized composition containing the phthalate-free, epoxidized plasticizer composition, as well as articles made from such compositions are also disclosed.
