摘要： The synthesis and characterization of star copolymers by living carbocationic copolymerization of statistical polymers comprising monomers of isobutylene (IB) and another monomer selected from the group consisting of styrene, isoprene and living carbocationically copolymerizable derivatives thereof is described. The poly(isobutylene-co-styrene) arms emanate from a calix[n]arene core where n preferably equals 8, forming an multi(octa)-arm star. The arms are advantageously fitted with crosslinkable termini such as allyl or hydroxyl end groups. The hydroxyl-terminated arm star copolymers are particularly suitable for use in coatings when reacted with crosslinking agents such as isocyanates.

摘要： There is provided a composition comprising a unique polymeric compound that provides a soft, flexible product. There is also provided a unique polymeric tampon applicator that is soft and flexible. When used as a tampon applicator barrel, the barrel is more comfortable and has improved ease of insertion. The polymeric compound primarily comprises a thermoplastic resin and a block copolymer that exhibit unique load, energy and modulus of elasticity properties. The polymeric compound should also include a plasticizer and a compatibilizer/flow modifier, and may include a slip/mold release agent, an antioxidant, and even a pigment. There is also provided a method for making the polymeric compound that will be formed into a product, such as an applicator or applicator barrel in which all of the above ingredients, except for the thermoplastic resin, are combined and formed into soft pellets. The soft resin pellets are then dry blended with pellets of the thermoplastic resin. The mixture of the thermoplastic resin pellets and the soft resin pellets are then melted and injection molded into the desired shape. There is thus provided a method of making a soft, polymeric tampon applicator or tampon applicator barrel.

Specifically, the thermoplastic block copolymers comprise hard segments of polystyrene combined with soft segments comprising 2 to 8 carbon atoms. Some of the physical characteristics of materials made by these composition are more desirable than the same physical characteristics of materials made of the polypropylene having less than 90 percent isotactic linkages used to make the composition and of the same physical characteristics of materials made of the thermoplastic block copolymer used to make the composition.
