Poly microfibrillar

A possible crystal structure for poly(p-benzamide) which is in accord with the measured repeat distance is shown in Fig. 8. It has been estimated that about 36 repeat units would have to be involved in one chain fold in this polymer. No obvious spacing corresponding to chain folds was found by low single X-ray measurements on highly oriented poly(p-benzamide) fibre. However, a strong equatorial streak was obtained which is consistent either with a microfibrillar structure having axially oriented fibrils or with axially oriented voids or regions of low density. ...

Those membranes, however, have a drawback as a second surgical entry is needed to remove the membrane after tissue regeneration has been achieved, if the membranes are not biodegradable. In order to preclude the surgical removal of an implant after doing its task, membranes made of bioabsorbable material, such as microfibrillar collagen, PLA, and poly(galactin) have been used.
