Abstract
In one aspect the invention provides a melt process for preparing a functionalized olefin multiblock interpolymer, said process comprising grafting onto the backbone of the olefin multiblock interpolymer at least one compound comprising at least one “amine-reactive” group to form a grafted olefin multiblock interpolymer, and reacting a primary-secondary diamine or an alkanolamine with the grafted olefin multiblock interpolymer, without the isolation of the grafted olefin multiblock interpolymer.
