Biodegradable Thermoplastic Elastomers and Pressure Sensitive Adhesives

Glucose, a widely available and inexpensive sugar molecule derived from corn, can be modified to produce a new, sustainable polymer for use in thermoplastic elastomers (TPEs) and pressure sensitive adhesives (PSAs). In a simple two-step synthesis, the glucose-based monomer GATA (glucose-6-acrylate-1,2,3,4-tetraacetate) produces diblock and ABA triblock copolymers via Reversible Addition-Fragmentation Chain Transfer (RAFT) polymerization. The resulting polymer combines unique elastomeric segments with glassy segments that physically cross link, resulting in a new family of elastomeric materials. The polymer also exhibits excellent thermal and adhesion properties as well as serviceable tensile strength and elasticity.

Sustainable Polymer

Today’s thermoplastic elastomers, used in a wide variety of applications, are typically derived from petroleum and are therefore not biodegradable. This technology uses bio-based and inexpensive materials to produce a new, sustainable polymer that could replace existing petroleum-based materials. This greener polymer also exhibits similar adhesion properties as petroleum-based PSAs.

BENEFITS AND FEATURES:

  • Simple two-step synthesis
  • Glucose derived starting materials
  • Controlled polymerization
  • Diblock and triblock copolymer synthesis
  • Greener elastomeric materials; biodegradable
  • Higher Tg glassy segment compared to styrene block copolymers commonly used in pressure sensitive adhesives

APPLICATIONS:

  • Thermoplastic elastomers (TPEs)
  • Pressure sensitive adhesives (PSAs)
  • Biomedical use, wound care and transdermal applications

Phase of Development Proof of concept. Polymers synthesized and characterized.
