International Classification:
C08F 10/00 C08J 3/24
Abstract:
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.

Andres Sustic - Odessa TX, US Nick Fowler - Odessa TX, US John Passmore - Odessa TX, US
International Classification:
C09J 123/14
Abstract:
A hot melt adhesive formulation includes 60 to 99 wt. of an amorphous propylene-co-hexene-1 polymer component based on the total weight of the hot melt adhesive without the use of flammable solvents, 20 to 80 wt % of hexene-1 co-monomer based on the total weight of the amorphous propylene-co-hexene-1 copolymer component, 20 to 80 wt. % of a propylene co-monomer based on the total weight of the amorphous propylene-co-hexene-1 copolymer component, and from 1 to 40 wt. % of a co-adjuvant based on the total weight of the hot melt adhesive. The hot melt adhesive formulation has rolling ball tack from 2 to 50 centimeters at ambient temperature after conditioning at ambient temperatures for 24 hours. The hexene-1 monomer to propylene monomer ratios are from 4:1 to 1:4.
Hexene-1 Containing Amorphous Polyalphaolefins For Improved Hot Melt Adhesives
- Odessa TX, US John Passmore - Odessa TX, US Nick Fowler - Odessa TX, US John J. DeCair - Odessa TX, US
International Classification:
C09J 123/22 C09J 11/06
Abstract:
Propylene-co-hexene-1-co-butene-1 terpolymers, made either with or without an in-reactor-added organosilicon external donor, are used in the formulation of improved-performance, APAO-based, hot melt adhesives. The addition of an external donor during the manufacture of hexene-1 based amorphous polyalpha-olefins (APAO's) results in products having enhanced physical and mechanical properties compared to similar adhesive products made without the addition of the external donor.
