20200109221 · 2020-04-09 ·

A method to make a high melt strength amorphous poly alpha olefin (APAO) includes blending APAO with a free radical initiator using a residence time from 0.1 minutes to 10 minutes at a temperature range from 300 degrees Fahrenheit to 400 degrees Fahrenheit, thereby forming an intermediate. A graftable monomer may then be added to the intermediate in a ratio from 0.1:100 to 2:100 at a temperature range from 225 degrees Fahrenheit to 400 degrees Fahrenheit using a residence time from 0.1 to 20 minutes, thereby forming a functionalized APAO. A multifunctional monomer in an amount ranging from 0.1% to 5% by weight of the functionalized APAO can be added to the functionalized APAO for 0.1 to 20 minutes at 200 to 400 degrees Fahrenheit, thereby forming a cross-linkable APAO. An acid neutralizer may be added to initiate crosslinking, making a crosslinked APAO with various degrees of crosslinking as observed by the changes in the melt viscosity. An amine coupling agent may be added to the cross-linkable APAO to control crosslinking.
