Abstract
The invention provides adhesives comprising at least one polymer component which contains at least 65 weight percent propylene, at least one nucleator and at least one functionalized wax. The inventive adhesives have increased heat resistance and decreased set-time, making them particularly well suited for assembly and packaging applications.
Claims6
A process for forming an adhesive comprising:
- (a) heating a polymer component which contains, in polymerized form, at least 65 wt % of propylene, based on the total weight of the polymer component to its molten state;
- (b) adding at least one nucleator and at least one functionalized wax into the molten polymer component, wherein the weight ratio of the nucleator to the functionalized wax ranges from about 1:500 to about 50:1;
- and
- (c) cooling the mixture.
