A potential energy function and an equation of state for amorphous polymers are developed by using a mathematical, quasi-lattice model to represent the molecular structure. The potential energy function, obtained by dividing a polymer chain into a li

Diffusion and solubility coefficients are presented for He, Ne, Ar, and N2 in three ethylene propylene copolymers, two styrene butadiene copolymers and a cis-polybutadiene at five temperatures in the range 0–50° C. The data were obtained by using

Mechanical properties of fiber reinforced composites depend on the formation of stable adhesive bonds between the constituents. In order to evaluate quantitatively the adhesion between liquid crystal polymer (LCP) fibers and a thermoplastic matrix of

In this paper we report on the morphogenesis of dental resins formed by a thermally initiated radical cross-linking copolymerization of model dental resins. These systems were considered reasonable model simplifications of the actual resins used in c

High resolution solid state 13 C and 29 Si CP/MAS NMR was used to investigate the grafting mechanism, morphology and interfacial mobility of polycarbonate (PC) oligomer and bisphenol A grafted onto silica surfaces. It was previously shown that interf

Vinyl esters are used widely as thermoset matrix materials for reinforced composites; however, they suffer from low-impact resistance. Substantial enhancement of the toughness of brittle polymers may be achieved by dispersing elastomeric inclusions o

A tribometer (model ISC-200PC) was modified to form a pin-on-disk type of wear test apparatus. A dental restorative material specimen was used as the pin and a diamond grinding wheel as the abrasive counterface. Both normal and friction forces were r

A method of evaluating the interfacial fracture toughness using a single-fibre composite test is proposed. In contrast with the existing techniques, the method takes into account the phenomenon of friction between the fibre and matrix in the debondin

A silicon tetrachloride-modified silane treatment of E-glass particles and fibers improved the hydrolytic stability of the glass reinforced composites by creating a water-resistant silane copolymer interphase of approximately 30 Angstroms thickness.

The compatibilization by transesterification of aromatic thermotropic liquid crystal polyesters (Ar-TLCP's) and TLCP's containing aliphatic ethylene-terephthalate (ET) linkages has been studied. Three Ar-TLCP's were mixed with two p(ET/HBA)'s, each h
