31. The oxide As 2 O 3 is polymeric , and a glass former. 32. Proanthocyanidins are mostly polymeric units of catechin and epicatechin. 33. These are obtained by various methods of fractionation or depolymerisation of polymeric heparin. 34. It can also include the use of polymeric gene carriers ( polyplexes ). 35. It is also responsible for the sequestering of the extracellular polymeric substance matrix. 36. Its oxidized and polymeric derivatives occur widely in nature. 37. They are polymeric in nature, and form filaments. 38. Hydrides in the transition metals and lanthanides are also typically polymeric covalent hydrides. 39. Rather, the species found in aqueous solution are monomeric and polymeric oxyanions. 40. Polymeric coatings are another area of applied grafting techniques.
