Реферат: Polymers containing α-methylene-lact(ones)(ams) such as α-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 α-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 α-methylene-lact(ones)(ams) such as a-methylenebutyrolactones containing (co)polymers.
