摘要: The invention relates to chemically bonded laminated structures and their production from oriented polymeric laminae. The bonds between the contacting lamina are formed by chemical reaction across their interface involving constituent molecular chains of each laminae. Three methods have been found for producing the bonds: (a) bringing the surfaces of the lamina in intimate contact to within 10.degree. C. and 100.degree. C. below the melting temperature of the surfaces; (b) interposing a coupling agent for the polymer molecules of the intimately contacting surfaces of each member into their interface and heating the laminate to a temperature effective to cause reaction of the coupling agent with the molecules of each; and (c) interposing a catalyst to promote chemical reaction of the molecules of each laminae with the molecules of intimately contacting lamina into their interface and heating to a temperature effective to cause reaction.Structures bonded may be from film sheets, strips or bands or they may be other configurations that have suitable surfaces for that intimate contact required.

摘要: The present invention relates to laminates of polyolefin laminae and strips chemically bonded in the solid state by reactions initiated by cross-linking catalysts interspersed at the interface of contacting laminae. Catalysts to initiate crosslinking reactions at temperatures below the melting point of the respective laminae are employed. A preferred application of the laminate is a chemically bonded structure of highly oriented, preferably uniaxially oriented film with the direction of orientation of uniaxial orientation at an angle to each other in successive laminae.

摘要: Fibers and plastic materials reinforced with these fibers which have a diameter that varies along the fiber axis are provided. The fibers increase the strength of the material by reducing fiber pull out from the plastic matrix. The variation in diameter results in an undulating surface on the fiber which locks it into the matrix.

摘要: A process of preparing a homogeneous amorphous polymeric blend of polyethyleneterephthalate (PET) and polybutyleneterephthalate (PBT) which includes intimately mixing the PET and PBT at a weight ratio of about 10:90-90:10, melting the mixture at 290.degree.-330.degree. C., cooling the mixture to 0.degree.--194.degree. C. by extruding it onto rollers maintained in a cooling bath and orienting the polymer of the resulting continuous shaped object at room temperature to a draw ratio of about 5:1, with subsequent annealing at about 120.degree.-180.degree. C. for about one hour.
