Enzymes are immobilized on non-porous glass fibers by coating glass fibers with a solution containing an enzyme and a soluble polymer and contacting the coated fibers with a controlled amount of cross-linking agent to obtain an immobilized enzyme having high activity and long endurance, and which provides a high percentage of conversion. The enzyme may be an amylase, the polymer a plyalkyleneimine and the cross-linking agent glutaraldehyde. Continuous immobilization can be carried out by moving continuous fibers to applicator stations for applying a solution of enzyme and polymer and a solution of cross-linking agent.

Enzyme immobilization on non-porous glass fibers

A process comprising synthesizing a liquid crystal polyester consisting essentially of recurring moieties of formulas: ##STR1## and moiety III or IV wherein III is ##STR2## wherein the mole ratio of moiety II to moiety III, when present, is 1:4 to 2:1 and wherein the mole ratio of moiety II to moiety IV, when present, is 2:8 to 1:9 and devolatilizing said liquid crystal polyester prior to shaping such polyester into an article and then shaping said devolatilized polyester into said article.
