Title (EN) POLYMER COMPOSITIONS AND A METHOD FOR ENHANCEMENT IN PHASE COMPATIBILITY OF ELASTOMERS WITH RELATIVELY RIGID POLYMERS
(FR) COMPOSITIONS POLYMERES ET PROCEDE D"AMELIORATION DE COMPATIBILITE DE PHASES D"ELASTOMERES AVEC DES POLYMERES RELATIVEMENT RIGIDES
Abstract: front page image
(EN)Thermoplastic compositions which contain, as principle ingredients, a relatively rigit polymer, such as polyvinyl chloride and/or chlorinated polyvinyl chloride and an EPM and/or an EPDM type elastomer. In addition to the above components, the composition can have incorporated therein a phase compatibility promotion agent, such as chlorinated polyethylene or poly (ethylene-co-vinyl acetate), or mixtures thereof. This phase compatibility promotion agent helps insure more uniform distribution of the elastomer throughout the relatively rigid polymer and improved cohesion of the resultant composition. Also disclosed are methods for enhancement in the compatibility of relatively rigid polymers and elastomers through the use of such phase compatibility promotion agents.
(FR)Compositions thermoplastiques qui comprennent, en tant qu"ingredients principaux, un polymere relativement rigide, tel qu"un chlorure de polyvinyle et/ou un chlorure de polyvinyle chlore et un elastomere du type copolymere d"ethylene et de propylene (EPM) et/ou du type copolymere d"olefine et de polyene (EPDM). En plus desdits composants la composition peut contenir un agent de promotion de compatibilite de phases, tel qu"un polyethylene chlore ou un poly (acetate d"ethylene-co-vinyl) ou des melanges de ceux-ci. Cet agent de promotion de compatibilite de phases permet d"assurer une distribution plus uniforme de l"elastomere au travers du polymere relativement rigide et une cohesion amelioree de la composition resultante. Sont egalement decrits des procedes d"amelioration de la compatibilite de polymeres relativement rigides et des elastomeres par l"utilisation de tels agents de promotion de compatibilite de phases.
