Abstract

A composition is provided, which comprises an ethylene/C3-C6 alpha-olefin interpolymer, and wherein the interpolymer comprises the following properties: a) an HCC value that meets the following equation: HCC (wt %)≥−648.6 [(wt %)(cc)/(g)]×(density)+569.4 (wt %); b) an aged flowability ≥130 g/sec.

Claims

exact text as granted — not AI-modified

What is claimed is: 
     
         1 . A composition comprising an ethylene/C3-C6 alpha-olefin interpolymer, and wherein the interpolymer comprises the following properties:
 a) an HCC value that meets the following equation:
   HCC (wt %)≥−648.6 [(wt %)(cc)/(g)]×(density)+569.4 (wt %);
 
   b) an aged flowability ≥130 g/sec.   
     
     
         2 . The composition of  claim 1 , wherein the ethylene/C3-C6 alpha-olefin interpolymer has an HCC value greater than, or equal to, 6.0 wt %. 
     
     
         3 . The composition of  claim 1 , wherein the ethylene/C3-C6 alpha-olefin interpolymer has an HCC value that meets the following equation:
   HCC (wt %)≥−648.6 [(wt %)(cc)/(g)]×(density)+570.9 (wt %).
   
     
     
         4 . The composition of  claim 1 , wherein the interpolymer further comprises an HCC value that meets the following equation:
   HCC (wt %)&lt;−463.4 [(wt %)(cc)/(g)]×(density)+413.8 (wt %).
   
     
     
         5 . The composition of  claim 1 , wherein the ethylene/C3-C6 alpha-olefin interpolymer has a melt viscosity from 2,000 cP to 50,000 cP at 350° F. (177° C.). 
     
     
         6 . The composition of  claim 1 , wherein the ethylene/C3-C6 alpha-olefin interpolymer has a density less than, or equal to, 0.910 g/cc. 
     
     
         7 . The composition of  claim 1 , wherein the ethylene/C3-C6 alpha-olefin interpolymer has a highest peak melting temperature less than, or equal to, 80.0° C. 
     
     
         8 . The composition of  claim 1 , wherein the alpha-olefin is a C6 alpha-olefin or a C3 alpha-olefin. 
     
     
         9 . The composition of  claim 1 , further comprising at least one tackifier and at least one oil. 
     
     
         10 . An article comprising at least one component formed from the composition of  claim 1 .
