  • Phenyl-endcapped depolymerizable polymer
    Patent number: 4987211
    Abstract: Phenyl-endcapped depolymerizable polymers are disclosed. The phenyl endcap eliminates the reactive terminal vinyl group resulting in increased depolymerization threshold temperatures and reduced residue after depolymerization. A multilevel metal lift-off process using the phenyl-endcapped polymers is disclosed. Additionally, the polymers are improved ceramic glass binder resins.
