摘要:
A transparent rubber-modified styrenic resin composition contains a rubber-particle-dispersed phase (A) and a copolymer matrix (B). The phase (A) contains a rubbery copolymer which is a block copolymer formed from 10 to 50 wt % of styrenic monomers and 90 to 50 wt % of dienic monomers, wherein the rubbery copolymer block contains polystyrene block in an amount of 5 to 35 wt % based on total weight of the rubbery copolymer. The copolymer matrix (B) is composed of 12 to 70 parts by weight of styrenic unit, 20 to 80 parts by weight of (meth)acrylate unit, 1 to 20 parts by weight of vinyl cyanide unit, and 0 to 40 parts by weight of other copolymerizable monomer units, based on 100 parts by weight of total monomer unit. The content of the copolymer matrix (B) having a molecular weight of 3,000null50,000 is in an amount of 15 to 50 wt %, based on the total weight of the copolymer matrix (B).
摘要:
Polymers containing null-methylenelact(ones)(ams) such as null-methylenebutyrolactones are useful in blends with other polymers. For examples such polymers which have reactive groups are toughened by mixing with a rubbery material which has complimentary reactive groups, or polymers containing repeat units derived from null-methylenelact(ones)(ams) are toughened by mixing with polymeric core-shell particles having an elastomeric core and a specified thermoplastic shell. The properties of thermoplastics are also improved by blending with null-methylenelact(ones)(ams) such as null-methylenebutyrolactones containing (co)polymers.

摘要:
The present invention relates to hot-coextrudable hot-melt pressure-sensitive adhesives particularly suitable for the production of multilayer films intended for what are called nullrepositionablenull packages that are opened and reclosed easily. The films used in these packages comprise at least three layers, namely an outer layer intended to be complexed thereafter, a sealing and separable layer, defining all or part of the internal surface of the package, and between them a hot-melt adhesive layer that joins them together. In this type of package, the adhesive plays an essential role insofar as, once the package has been opened by the end user, the quality of the reclosure and of the reopening will depend on the performance of the adhesive, which is of course a pressure-sensitive adhesive, that is to say an adhesive that adheres simply by manual pressure.
