Abstract Autohesion is a particular form of adhesion. It occurs when two surfaces of the same elastomer are pressed together. The increase of the autohesive strength, with the increase of contact time, is caused by interdiffusion of mobile macro-molecule chain ends across the boundary face. After a certain time of contact, the contact zone disappears and a homogeneous system is obtained. The autohesive strength is then equal to the bulk strength of uncrosslinked elastomers. The autohesion of polybutadiene, butadiene-acrylonitrile copolymers, ethylene-propylene copolymers and polychloroprene was studied. The influences of microstructure, polar side groups, cristallinity, contact time, test rate, and the influence of solvents on autohesion were investigated in detail.

We present applications of a model developed to describe unfolding in macromolecules under an axial force. We show how different experimentally observed force-extension behaviors can be reproduced within a common theoretical framework. We propose that the unfolding occurs via the motion of a folded/unfolded interface along the length of the molecule. The molecules are modeled as one-dimensional continua capable of existing in two metastable states under an applied tension. The interface separates these two metastable states and represents a jump in stretch, which is related to applied force by the worm-like-chain relation. The mechanics of the interface are governed by the Abeyaratne-Knowles theory of phase transitions. The thermodynamic driving force controls the motion of the interface via an equation called the kinetic relation. By choosing an appropriate kinetic relation for the unfolding conditions and the macro-molecule under consideration, we have been able to generate a variety of unfolding processes in macromolecules.

To reduce costs and obtain excellent performance, acrylic modified lignin sulfonate instead of butyl methacrylate stearyl methacrylate was prepared to oil absorption resin. And 1, 4-butylene glycol dimethacrylate as a crosslinking agent, 2,2’-azo-bis-(2-methylpropionitrile) as the initiator, with butyl acrylate to product the high lignin oil-absorbing resin, selected the best scheme for preparing by the orthogonal method, and the different concentrations of lignin and the best resin properties determined by SEM and its oil absorption test. Experimental results show that the resin has the high oil absorption properties,the maximum absorption of 20 times, and the suction speed is fast that 90min to reach saturation; It also has other characteristics,such as inexpensive cost, lightweight, easy recycling and disposal, reusable and so on.
