Abstract: Hydroxyl-containing filler reinforced thermoplastic polymers, such as polyolefins, are disclosed having improved physical properties such as impact strength, break strength and flexural modulus. The filler is compatibilized with a thermoplastic polymer containing labile atoms by mixing the two together in the presence of a coupling agent, such as maleic anhydride and a free radical initiator such as a peroxide catalyst. In a preferred embodiment, clay is coated with polyethylene by mixing the two in the presence of a peroxide catalyst and maleic anhydride and the coated filler is then compounded with additional polyethylene. In another preferred embodiment, a filler is coated with a polyolefin having a high melt index and the coated filler is then compounded with a polyolefin having a lower melt index. Also disclosed are various means for molding the compatibilized composites of this invention.

Abstract: Molecularly oriented films, and compositions used therein, comprise blends of a first EVA copolymer having a relatively low VA content, and a second EVA copolymer having a relatively high VA content. The blend exhibits a balance of properties which permit ready processability for orientation, while affording high levels of strength, particularly at elevated temperatures. Consequently laminates may be produced which are well suited for shrink packaging of meat, especially when a high oxygen barrier resin provides one layer thereof.

Abstract: Novel copolymers of maleic anhydride and dimers of cyclic conjugated dienes such as cyclopentadiene in which the maleic anhydride/dimer mole ratio ranges from 1/1 to 2/1. The copolymers are prepared by heating the dimer and maleic anhydride at a temperature of 50.degree.-170.degree. C., in the presence of a polar solvent and a free radical precursor which has a half-life of no more than 2 hours at the reaction temperature.

Abstract: Novel copolymers of maleic anhydride and the endo and exo cyclic adducts of maleic anhydride and cyclic conjugated dienes such as cyclopentadiene. The copolymers are prepared by heating either of the cyclic adducts and maleic anhydride in the presence of a free radical precursor, such as a peroxygen compound, at a temperature at which endo-exo isomerization of the adduct occurs.
