AB In an effort to understand the influence of the shape and area of the nanoclay type used inthe in situ polymerization process, two different types of clays (fibrillar and laminar) wereemployed to obtain nanocomposites. The preliminary results demonstrated that a needlelikeshaped clay promotes higher molar mass and better mechanical properties comparedwith laminar clay. The ultra-high molecular weight of sepiolite/nanocomposites introducessignificant problems with processability. Therefore, a new method of polymerization wasdesigned to include two significant changes. The first change was related to the use of anon-isothermal temperature profile and the second to the addition of an additional amountof non-anchored co-catalyst leading to materials with higher fluidity.
