Document Type and Number:
WIPO Patent Application WO/2024/020827
Kind Code:
A1
Abstract:
A process for manufacturing a grafted polyolefin having improved yellowness properties, the process including reacting an admixture of: (i) at least one polyolefin; (ii) at least one monomer; wherein the at least one monomer is selected from one or more acid compounds having the following general chemical Formula (I) or Formula (II); wherein in Formula (I) and Formula (II) either R1 or R2 is H, with the proviso that both R1 and R2 is not H; wherein at least one of R1 and R2 is an alkyl or an alkenyl with a carbon number of from 1 to 20; and wherein R1, R2, or both R1 and R2 may further include an ester, a heteroatom, an aromatic, or a halogen; and (iii) at least one free radical initiator to form a grafted polyolefin; wherein the grafted polyolefin has a yellowness index, YIE313, of < 30.
