摘要： The invention includes a process comprising steps of (1) forming a admixture of (a) a vinyl aromatic polymer and (b) a coupling amount of at least one poly(sulfonyl azide); (2) introducing the vinyl aromatic polymer or admixture into a melt processing device; (3) melting the vinyl aromatic polymer or admixture, and thereafter (4) exposing the admixture to a temperature, hereinafter, melt process temperature, sufficient to result in coupling of the vinyl aromatic polymer. The invention also includes a process of increasing the molecular weight of a vinyl aromatic polymer by heating an admixture of at least one vinyl aromatic polymer and a coupling amount of at least one poly(sulfonyl azide). Alternatively the invention is a process comprising steps of (1) forming, under a first pressure, a mixture of a vinyl aromatic polymer, a blowing agent and at least one poly(sulfonyl azide), with the mixture at a temperature at which the viscosity of the mixture is sufficient to retain the blowing agent when the mixture is allowed to expand; (2) extruding the mixture into a holding zone maintained at a temperature and second pressure which does not allow the mixture to foam, the holding zone having an outlet die defining an orifice opening into a zone of a third pressure lower than the first or second pressures at which the mixture foams, and an openable gate closing the die orifice; (3) periodically opening the gate; (4) substantially concurrently applying mechanical pressure by a movable ram on the mixture to eject the mixture from the holding zone through the die orifice into the zone of third pressure, at a rate greater than that at which substantial foaming in the die orifice occurs and less than that at which substantial irregularities in cross-sectional area or shape occurs; and (5) permitting the ejected mixture to expand unrestrained in at least one dimension to produce an elongated thermoplastic cellular body. The invention also includes any composition comprising a product formed by a process of the invention, said composition preferably comprising a foam or polymer and any article formed from such a composition.

The invention also includes any composition made by the process of the invention and any article made from the composition as well as processes for making the articles, particularly melt processing (especially where the article is formed from a melt of a composition of the invention), more preferably selected by molding, blow molding or extrusion blow molding the composition. The invention also includes the use of a composition of the invention in any of these processes.
摘要翻译：本发明包括一种制备偶联聚合物的方法，包括加热含有（1）至少一种包含乙烯和任选至少一种选自具有至少3个碳原子的α-烯烃的共聚单体的聚烯烃，二烯及其组合的混合物的混合物，所述聚烯烃具有小于或等于约3的分子量分布和（2）偶联量至少一种聚（磺酰基叠氮化物）至少达到聚（磺酰基叠氮化物）的分解温度足够分解至少约 80重量％的聚（磺酰基叠氮化物）并且足以产生偶联的聚合物; 特别是当聚烯烃是在单中心催化剂（过渡金属如Va或Cr，金属茂或约束几何形式）存在下乙烯和任选的至少一种其它α-烯烃聚合的产物时。聚（磺酰基叠氮化物）的量优选为聚烯烃的约0.01至约5重量％。聚（磺酰基叠氮化物）和聚烯烃优选在至少分解温度和大于约150℃的温度下进行反应。本发明还包括通过本发明的方法制备的任何组合物和由组合物制成的任何制品以及工艺用于制造制品，特别是熔融加工（特别是在由本发明的组合物的熔体形成制品的情况下），更优选通过模制，吹塑或挤出吹塑该组合物来选择。本发明还包括在任何这些方法中使用本发明的组合物。
