Abstract

A process of forming a macromolecular block copolymer includes forming a first high molecular weight polymer of a first length. The first high molecular weight polymer includes a first set of side-chain functional groups and has a first characteristic rigidity value along the first length. The process also includes forming a second high molecular weight polymer of a second length. The second high molecular weight polymer includes a second set of side-chain functional groups and has a second characteristic rigidity value along the second length that is less than the first characteristic rigidity value. The process further includes bonding the second high molecular weight polymer to the first high molecular weight polymer.

First claim

The invention claimed is:

1. A process of forming a macromolecular block copolymer, the process comprising:
forming, by polymerization, a first extruded polymer of a first length, the first polymer including a first set of side-chain functional groups and having a first rigidity along the first length;
forming, by polymerization, a second extruded polymer of a second length, wherein the second polymer includes a second set of side-chain functional groups and has a second rigidity along the second length that is less than the first rigidity; and
bonding covalently at least a portion of the second polymer to the first polymer.

2. The process of claim 1 , wherein the first extruded polymer includes a polystyrene (PS) material, and wherein the second extruded polymer includes a linear low density polyethylene (LLDPE) material.

3. The process of claim 1 , wherein the first set of side-chain functional groups include amine groups, norbornene groups, hydroxyl groups, or a combination thereof.

4. The process of claim 1 , wherein the second set of side-chain functional groups include amine groups, norbornene groups, hydroxyl groups, or a combination thereof.

5. The process of claim 1 , further comprising:
forming, by polymerization, a third extruded polymer of a third length, wherein the third extruded polymer includes a third set of side-chain functional groups and has a third rigidity along the third length that is different from the second rigidity; and
bonding covalently at least a portion of the third extruded polymer to the polymer.

6. The process of claim 5 , wherein the third rigidity corresponds to the first rigidity.

7. The process of claim 5 , wherein the third set of side-chain functional groups correspond to the first set of side-chain functional groups.

8. The process of claim 5 , wherein the third set of side-chain functional groups include amine groups, norbornene groups, hydroxyl groups, or a combination thereof.

9. The process of claim 5 , wherein:
the first extruded polymer includes a polystyrene (PS) material;
the second extruded polymer includes a linear low density polyethylene (LLDPE) material; and
the third extruded polymer includes the PS material.

10. A process of forming a macromolecular block copolymer, the process comprising:
forming, by polymerization, a polystyrene (PS) polymer of a first length, the PS polymer including a first set of side-chain functional groups and having a first rigidity along the first length;
forming, by polymerization, a linear low density polyethylene (LLDPE) polymer of a second length, wherein the LLDPE polymer includes a second set of side-chain functional groups and has a second rigidity along the second length that is less than the first rigidity; and
bonding covalently at least a portion of the LLDPE polymer to the PS polymer.

11. The process of claim 10 , wherein the first set of side-chain functional groups include amine groups, norbornene groups, hydroxyl groups, or a combination thereof.

12. The process of claim 10 , wherein the second set of side-chain functional groups include amine groups, norbornene groups, hydroxyl groups, or a combination thereof.

13. The process of claim 10 , further comprising:
forming, by polymerization, a second PS polymer of a third length, wherein the PS polymer includes a third set of side-chain functional groups and has a third rigidity along the third length that is different from the second rigidity; and
bonding covalently at least a portion of the second PS polymer to the LLDPE polymer.

14. The process of claim 13 , wherein the third set of side-chain functional groups include amine groups, norbornene groups, hydroxyl groups, or a combination thereof.
