Blends of poly[alpha-methylenelact(one)(am] homo- and copolymers |
摘要 |
Polymers containing alpha-methylenelact(ones)(ams) such as alpha-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 alpha-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 alpha-methylenelact(ones)(ams) such as alpha-methylenebutyrolactones containing (co)polymers.
