    摘要： A golf ball is composed of at least a pair of adjacent concentric solid layers or three adjacent concentric solid layers. In the former case, the outer solid layer is composed of a matrix and non-metallic high-hardness grains having hardness higher than that of the matrix which has a Shore D range of 36-40. In the later case, the intermediate solid layer is composed of a matrix and high-hardness grains having hardness higher than that of the matrix. The high-hardness grains have a Shore D hardness in the range of 50-70 and penetrate the corresponding solid layer in normal directions. The golf ball can provide a player with different feels on impact depending on the direction of an external force applied thereto when the golf ball is hit.

    摘要： A polymeric composite structure having a polymeric shell layer with a finish-side and a non-finish side and a cross-linked thermosetting polymeric backing layer and method of manufacturing thereof is provided. The cross-linked thermosetting polymeric backing layer is simultaneously molded to conform to the shape of and bonded directly to essentially the entire non-finish side of the polymeric shell layer. The method includes forming the polymeric shell having a finish-side and non-finish side into a suitable shape, placing the shell into a mold, and introducing an uncured blended mixture of unsaturated thermosetting polymeric backing material and cross-linking promoter into the mold to force the backing material to directly coat the non-finish side of the shell. Curing the molded thermosetting polymeric backing material at a suitable temperature and sufficient time allows hardening and cross-linking of the thermosetting polymeric material and bonding directly to the non-finish side of the polymeric shell to permit demolding of the composite structure without damage.

    摘要： Plastic containers having improved physical properties are prepared from a composite billet having an outer peripheral area composed of a thermoplastic resin and an inner central core portion composed of the thermoplastic resin modified with a material which imparts improved physical properties such as reduced gas permeability or increased stiffness or rigidity to the resin. The composite billet is molded into a container wherein the billet core is formed into the sidewalls and bottom of the container and the peripheral portion is formed into a flexible thermoplastic flange surrounding the open end of the container which can be doubled seamed to a metal end closure without fracture.
