Abstract
Pressure-sensitive adhesive compositions including a copolymer comprising a first divalent monomer unit represented by the structure (I) wherein Y is a heterohydrocarbyl group having up to having up to 18 carbons; and R1 is —H or —CH3; and a second divalent monomer unit represented by the structure (II) wherein X is a hydrocarbylene group having up to 5 carbons; R1 is —H or —CH3; and each R2 and R3 is independently —H or a hydrocarbyl group having up to 8 carbons. Articles including the disclosed pressure-sensitive adhesive compositions and methods of preparing the disclosed pressure-sensitive adhesive compositions are provided.

A pressure-sensitive adhesive composition comprising:
- a copolymer comprising:
- a first divalent monomer unit represented by the structure
- wherein
- Y is a heterohydrocarbyl group having up to having up to 18 carbons;
- and
- R1 is —H or —CH3;
- and
- a second divalent monomer unit represented by the structure
- wherein
- X is a hydrocarbylene group having up to 5 carbons;
- R1 is —H or —CH3, and
- each R2 and R3 is independently —H or a hydrocarbyl group having up to 8 carbons.
A method of making a pressure-sensitive adhesive composition, the method comprising:
- combining an initiator, an optional chain transfer agent, an optional solvent, and a copolymer comprising:
- a first divalent monomer unit represented by the structure
- wherein
- Y is a heterohydrocarbyl group having up to having up to 18 carbons;
- and
- R1 is —H or —CH3;
- and
- a second divalent monomer unit represented by the structure
- wherein
- X is a hydrocarbylene group having up to 5 carbons;
- R1 is —H or —CH3, and
- each R2 and R3 is independently —H or a hydrocarbyl group having up to 8 carbons to provide the pressure-sensitive adhesive composition.
