Polymeric resin for dielectric applications

A polymer comprising a copolymerization product from a mixture comprising:

• (a) 10-50 mol %, based on the total monomers present in the copolymerization, of at least one addition polymerizable arylcyclobutene monomer of Formula A-1-a,
• wherein:
• Ar is a substituted or unsubstituted carbocyclic aryl or a substituted or unsubstituted heteroaryl group;
• Q is a covalent bond, O, S, or NRa;
• Ra is selected from the group consisting of hydrogen, deuterium, substituted or unsubstituted carbocyclic aryl, and substituted or unsubstituted heteroaryl;
• R5-R7 are the same or different and are independently selected from the group consisting of hydrogen, deuterium, alkyl, alkoxy, a substituted or unsubstituted carbocyclic aryl group, and a substituted or unsubstituted heteroaryl group;
• R8 is the same or different at each occurrence and is selected from the group consisting of alkyl, alkoxy, a substituted or unsubstituted carbocyclic aryl group, and a substituted or unsubstituted heteroaryl group;
• and
• a is an integer from 0 to 4;
• (b) 15-50 mol %, based on the total monomers present in the copolymerization, of at least one addition polymerizable diene monomer;
• (c) 15-60 mol %, based on the total monomers present in the copolymerization, of at east one addition polymerizable aromatic vinyl monomer;
• and
• (d) 3-10 mol %, based on the total monomers present in the copolymerization, of at least one addition polymerizable vinyl substituted C3-12 heterocycle monomer.
