  The processability of an uncured soft elastomer is improved by blending the elastomer under shear conditions with a terpolymer of ethylene with carbon monoxide and with a copolymerizable ethylenically unsaturated monomer in the presence of a crosslinking agent for polymer (T) which does not substantially cure elastomer (E). Gel resulting from crosslinking polymer (T) improves the properties of the blend as compared with the soft elastomer alone. When elastomer (E) and the crosslinking agent for polymer (T) risk undergoing a reaction which would result in substantially crosslinking elastomer (E), one may substitute another soft elastomer (E,) for elastomer (E) to avoid this undesirable result and then blend the resulting composition with elastomer (E).

  在剪切条件下，将未固化的软弹性体与乙烯与一氧化碳的三元共聚物以及可共聚的乙烯不饱和单体混合，在聚合物（T）的交联剂存在的情况下，改善未固化软弹性体的可加工性，而聚合物（T）不会对弹性体（E）产生实质上的固化作用。与单独的软弹性体相比，交联聚合物（T）产生的凝胶可改善混合物的性能。当弹性体（E）和用于聚合物（T）的交联剂可能发生反应，导致弹性体（E）基本交联时，可以用另一种软弹性体（E, ）代替弹性体（E），以避免这种不良后果，然后将所得组合物与弹性体（E）混合。

  A poly(vinyl chloride) product is provided containing as a permanent plasticizer, a copolymer of vinyl acetate and ethylene which is copolymerized in the presence of porous particles of the PVC. The copolymerization is carried out in either suspension or emulsion and under conditions which provide a copolymer containing 60 to 85 wt% vinyl acetate in amounts from about 20 to 60 wt% of the vinyl acetate/ethylene copolymer in the final composition. A free flowing powder is formed which can be used for PVC compounding operations. If over 60 up to 80 wt% of the composition contains the copolymer, the product is a reinforced VAE dispersion.
