Process for bonding elastomers to metals [PDF]
, 1993 A process for bonding elastomeric material to a metal part includes coating a heat curable adhesive on the surfaces of the metal part to be bonded. The metal part is placed in a mold, a bottom plate and an upper transfer pot of a transfer molding machine

Journal of Applied Polymer Science, EarlyView.Influence of acrylonitrile (ACN) content on the processing behavior and morphological development of PA/NBR thermoplastic vulcanizates. Torque‐time profiles, SEM, and SEM/AFM images show that an intermediate ACN level (38%) promotes improved phase dispersion and morphological uniformity, especially with increased processing time, resulting in the most ...

From Collapse to Freezing in Random Heteropolymers
, 1997 We consider a two-letter self-avoiding (square) lattice heteropolymer model of N_H (out ofN) attracting sites. At zero temperature, permanent links are formed leading to collapse structures for any fraction rho_H=N_H/N. The average chain size scales as R

Journal of Applied Polymer Science, EarlyView.This study explores scalable methods of incorporating graphene nanoplatelets into SBR latex with or without a surfactant, using either powder or a masterbatch. Results show that combining a masterbatch with the surfactant DTAB improves vulcanization speed, mechanical strength, hardness, thermal conductivity, and resistance to aging.

Membrane Polymers for the Pervaporative Separation of Polar Organics: Methanol and Acetonitrile
Journal of Applied Polymer Science, EarlyView.We tested seven polymers as membranes for the pervaporative separation of methanol‐acetonitrile mixtures. Chloroprene rubber, silicone rubber, and Matrimid showed effective separation by favoring acetonitrile transport, enabling azeotrope breaking. Plasticization was assessed using Broadband Dielectric Spectroscopy.

Journal of Applied Polymer Science, EarlyView.The use of polychloroprene is common in elastomeric adhesives. This study highlights the possible substitution of zinc oxide curing systems to a less hazardous metal complex, also evaluating the changes that higher surface area fillers can bring to the adhesive.
