Patent ID: 8318864

Claim:
A composition comprising: at least one silane-grafted ethylene/α-olefin multi-block polymer, wherein the silane-grafted ethylene/α-olefin multi-block polymer is formed from an ethylene/α-olefin multi-block polymer having (i) a polydisperse block number distribution and a polydisperse distribution of block sizes; (ii) a melt viscosity less than 50,000 cP at 177° C.; and (iii) at least one melting point, T m , in degrees Celsius, and a density, d*, in grams/cubic centimeter, and wherein the numerical values of the variables correspond to the relationship: T m >−2002.9+4538.5( d *)−2422.2( d *) 2 , and wherein ethylene/α-olefin multi-block polymer has a M w /M n from 1.7 to 3.5.
