Can phenol polymerize
WebNov 10, 2024 · Phenolic resin is a thermoset polymer and it exhibits brittle nature at room temperature (Frollini et al. 2013). Generally, phenolic resin can be efficiently utilized in high temperature application and thermal insulators. The raw materials for phenolic resin (phenol and formaldehyde) were derived from non-renewable resources. Webphenol polymerization of 84% was achieved at 100 mg/l using free HRP enzyme and phenol degradation of 62% was observed using Immobilized HRP enzyme bed reactor. They also observed that as the concentration of phenol increased, there was reduction in phenol polymerization efficiency. Effect of reaction condition on phenol
