ABSTRACT:
A method for in situ expansion for example in a car pillar includes a base polymer derived of ethylene and an olefinically unsaturated acrylic ester with an MI of from 0.1 to 6 and containing from 10 to 40% of ester derived units. The composition is foamed and cross-linked to adhere to the car pillar interior and provide closed cell foam acting as a moisture-sound barrier.
