Ordered architectures in acrylic polymers
First Claim
1. An ordered polymer comprising at least two different blocks, including one or more blocks A placed at a first region within the polymer and one or more blocks B placed at a second region within the polymer, and at least one reactive functional group apportioned between the blocks A and B wherein an amount of the at least one reactive functional group in both blocks A and B is apportioned between the blocks A and Bin an apportionment ratio of from about 6:
- 1 to about 10,000;
1,wherein the glass transition temperature (Tg) of the ordered polymer is about −
45°
C. to about −
60°

Abstract
Polymers having ordered architectures and one or more reactive functional groups incorporated in select blocks or regions of the polymer in particular proportions relative to other regions in the polymer, are described. The polymers are well suited for use in adhesive compositions, and particularly for pressure sensitive adhesive compositions. In addition, various methods for forming the noted polymers and adhesive compositions utilizing the ordered polymers are disclosed.
